1998 Toyota RAV4 Q&A
1998 Toyota RAV4 Question: No heat or A/c
I've already submitted a question concerning the RAV4 overheating - engine light comes on - thermostat was replaced - sensor replaced - gas cap is ok - still overheats. When the thermostat and sensor was replaced - car ran ok for about a week and then wham - engine light back and on and temp gauge shot through the roof - when the thermostat was changed - there was no A/C???? - don't know if it's all related HELP!!! - gbgoul
Really need to get the check engine code, it may or may not be related to the over heating issue. Also, like I said in the first answer, make sure that your cooling fan is working and then do a chemical block test to ensure the head gasket is still sealing properly. - dandd
When Engine Computer detects overheat condition it will disable AC System. - tamaples
Hello gbgoul, I agree with dandd. First I'd retrieve the engine's trouble codes registered in the vehicle's computer to properly diagnose the problem that triggers the CEL. Inoperative cooling fan could cause a rapid engine overheat. - fernando
The controls light up normally and the fan works but no hot or cold air...Thanks!
