Hello everyone. I have a 2 door, 1999 Toyota rav4 that never had a cruise switch when I bought it. I just went to the wreckers and bought a used cruise control switch out of a 99 and installed it and it fits perfect but I still don't have anything. My question is maybe there is a fuse out and it is not getting power so would anyone know which fuse controls the cruise control and where it is located? I know there is fuses in both the engine and under the dash but i can't find anything that says cruise on it. Also is there anything else I have to do to get the cruise working? Thanks for your help
Where are the fuse(s) for the cruise control on a 1999 rav4?

Was your Rav4 equipped with cruise control, the switch went bad or missing and you replaced it with one from a junkyard?
Or it never had cruise control and you just bought the switch?
If it's the latter, then there are more parts you need to buy in order to make this work. Here is a recent thread concerning a DIY cruise control install on a RHD Rav4:

Hi Mick, Thanks for your reply. I just bought this rav about a year ago and it never had the main cruise control on the switch at all so I am not sure if it ever worked or not. One day I was poking around the engine and saw the cruise control mechanism and I know that some companies install everything but the main cruise control switch as it is cheaper for them to do it that way and they if you opt to have cruise they just put on the switch. Thats what I was hoping for anyway. So I went to the junkers and bought a cruise switch from a 99 Rav and installed it but I have nothing. No lights and no response of any kind and thats what got me thinking that a fuse or something electronic is needed to activate the cruise that they didn't install is till needed. I will go read the message you sent. thanks

Also a friend of mine said that it could be the "cruise control release switch" so I crawled underneath to make sure I even have one and I do. Whats the odds that if it was never used that it is buggered? I guess it still moves every time I push the clutch in so .....anyway someone help!!!...lol

update deux... there are actually 4 fuses that control the cruise control. The 10 amp guage fuse, the 15 amp dome fuse located in the engine compartment and the ECU-IG 7.5 amp fuse along with the 10 amp stop fuse. There is also a switch on the clutch as well as the break that could also be faulty. I am writing this in case someone else has the same issues and they can look this up.
Hi TonyE, Can you confirm that the actuator is present? If the actuator is installed, it will be in the engine bay, driver's side, rear, near the top. The photo below shows the actuator circled in purple:

The actuator will have two cables connected to it. One cable goes through the firewall to the gas pedal. The other cable loops around some then goes to the throttle body. If the actuator is present, is its pigtail plugged in?
Also, have you confirmed that the cruise control ECU is present? It should be behind the glove box. From Mick, see
While you are figuring out the cruise control system, it is probably best to bypass the cruise control clutch switch. In other words, unplug the switch. With a piece of wire, short its connector's two terminals.

Hi Tony, How about the cruise control ECU? Is it present? If you are not sure what it looks like, search for "cruise control ecu" for a 1999 Rav4 at ebay, and photos will come up.
Back in the 1990s, some Honda Civic sub-models came with cruise controls, and some did not. On a sub-model that did not have cruise control, a person had to buy the actuator, cruise control ECU, switch and more and then install them. (I actually did this using salvage yard parts.) I would be surprised to learn that a Rav4 that at initial sale did not have cruise control had all the parts except the switch.
If you are handy with a multimeter and can read electrical wiring diagrams, then figuring out what is wrong is do-able and not too labor intensive.

Where is the actuator's pigtail suppose to be plugged in to? I see the two cables coming out but thats about it. Okay tomorrow I will disconnect the clutch switch and short it out. I think the ecu is on the passenger side wall behind the plastic and I think I saw it there . There is also a another fuse box there beside the ecu. As far as I know I think I have all the parts. Another guy I know said that he has done this to one of his older ravs which was just buy the switch and install it and then everything worked perfect so thats what I was hoping. I suck with a multi meter and where to start would be my question. Thanks for your help Elle!!! so if i don't do the multi meter whats next?

So it has the actuator with the pigtail plugged in. It has the ECU on the passenger side of the car. It has the sensors on the clutch as well as the brake. It has the main cruise control now that I put it in and the 4 fuses for it are there and are working so now what? It means one of those components or more are not working or plugged in right? It means "meter time?"
Yes, by "pigtail" I meant the wires coming out of the actuator.
I think there is also a switch on the brake pedal. Its purpose is to deactivate the cruise control when one presses on the brake pedal.
I agree it is most likely that either (1) one of the parts (actuator; switch on the steering column; brake switch; clutch switch; the cruise control ECU) is not plugged in; or (2) one of these parts has failed.
Can you photograph the front and back of the switch mounted on the steering column and post these photos here? The first switches installed typically have the back of the casing coming off, due to poor design. This results in an internal electrical disconnect. Subsequently Toyota re-designed the switch casing so a screw holds everything together. I would like to see if you have an older switch or a newer one.
I bought my 1998 Rav4 last year. The cruise control did not work. Later I googled and learned about the back of the switch's casing coming off. When I pressed the back of the switch's casing, the cruise control worked. Ultimately I just bought a newer switch from a salvage yard, with a screw in the back holding all together firmly.
My next steps would be as follows:
-- Check that all major components are plugged in. If everything is plugged in, and the cruise control system still does not work, continue.
-- I think switches fail more often than actuators or computers. So check the three main switches. Electrically bypass the clutch pedal switch and the brake pedal switch. Does the cruise control work? If not, continue with the steps below. If the cruise control works with the clutch pedal switch and brake pedal switch bypassed, then figure out which one is not working, and replace it.
-- Get a digital multimeter. I like my $20 (or so) Craftsman multimeter a lot. Read the multimeter's instruction manual once quickly? Practice the continuity test feature with a bare piece of wire. Practice the DC voltage feature by touching one probe to the positive terminal of the battery and the other to the negative terminal and look for 12 volts. The ohmmeter feature is likewise pretty straightforward once you have practiced a bit.
Come up with ways to put, say, a paper clip or scrap of wires in the end of female-type plugs so you can take your readings. For male-type plugs, maybe get some small alligator clips to help with your readings.
-- Go to page 149 (pdf page 147) of the manual I linked above. Look over the tests, listed near the bottom of this page, for the cruise control switch mounted on the steering column. On page 151 (pdf page 149) a drawing of the switch's connector, labeled C12, appears. The three terminals on the connector are terminal 3, terminal 4, and terminal 5. Unplug the switch. Match the terminals on the actual connector with the ones on the drawing. Try the tests on page 149.

Thanks again for your help. The only thing that I am not 100 percent positve about os the ECU for the cruise. IN the picture it shows it behind or below the glove box but when I take the glove box out there is nothing there. There is an ECU just above the JB#4 panel just below and right of where the diagram shows it. The one on the diagram shows the ECU is there for the electric locks but I don't have electric locks so I am assuming that that ECU is the one for the CRuise control. Does that make sense or is there a way to tell what ECU is for what accessory? When I looked for the ecu behind the glove box I didn't see oner and I did not see any wires hanging there that needed to be plugged in so I just assumed that the one on the right was the ecu for the cruise. Maybe it doesn't have the ecu?
Here's a drawing that I think is better:
![Image]()
A photo of an uninstalled 1998-2000 cruise control ECU (also known as "cruise control module") currently appears at https://www.ebay.com/itm/2000-Toyot...=937873315&hash=item2acc499a85:g:jL8AAOSwjVhdDVZx:sc:USPSFirstClass!87501!US!-1
and with bracket:
Check the part number printed on what you think may be the cruise control. Is it one of the following
88240-0W022
88240-0W010
88240-0W020
88240-0W021?
I suppose it is possible someone started installing cruise control but did not get to the point of purchasing the cruise control ECU (module). If you buy one from a salvage yard, make sure it is for your manual transmission Rav4. The auto tranny cruise control ECU (module) is different. If it is not already installed, then wiring may be a challenge.

I just took the glove box out looking again for the ECU for the cruise and I can't see anything that looks like the pics that you sent me. The only thing that I can see in there that even looks close to an ECU is the box on the picture and it does not have writing on it saying anything except for a white tag and some numbers on it like "VC-?20B" "9806-18A0225" "assembled in the USA. I can't see where that ECU metal holder would bolt into and I cannot see any loose connection wires that would go to the ECU. Other than that things are good....lol. So I don't want to go out and buy a ECU if the car is not wired for it. Shouldn't the wire/plug be there someone and maybe they tucked it up and away someone where? so now what? I will go back out and look some more.
