Hi. I have a 1996 3 door RAV4 and have a problem in that all dash functions including indicators cut out periodically especially when hitting bumps on road. This is accompanied by a crackling sound coming from under the dash. It would appear to come from the ecu type box just in front of the door pillar as if I thump the panel under the dash near it it sometimes works again. Or if I switch off ignition and back on again it sometimes clears. It's obviously a bad connection somewhere but as there are dozens of connections on the ecu thing trying to find it is not easy. The problem was possibly caused by a leak from a new windscreen fitted about 18 months ago. Have sealed the leak but the damage had obviously been done.
Has anybody had this problem and how did they fix it.
Part of the problem is the lack of access and visibility.
