My Rav4 2007 has an AC problem

Azikag · 01-16-2013, 12:57 PM

Hello,

My Rav4 has an AC problem. When refilled it works for 3 days cooling the car but thereafter, it blows hot air. I have taken it for checking at the Toyota dealer and was told to change the compressor which I did, but that has not solved the problem. Anyone know how I can deal with this problem? I need a functioning AC. Help. Thanks, Ems.

Apparently it has one or more leaks allowing the refrigerant to escape the closed system. Have a specialist check it for leaks.

There are florescent dyes which can be used by injecting them into the system to detect refrigerant leaks and there are leak detecting instruments which can be obtained (rather pricey to buy - maybe it would be possible to rent one even in Uganda). If the leak is with the evaporator it will be more difficult to locate since that part is located behind the vehicle instrument panel (dash). As RF suggests it probably would be best to have a trustworthy technician attempt to locate the leak, if that is possible.
