Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Has anyone looked at replacing the AC amplifier? It's likely that the compressor isn't coming on because the amplifier isn't sending the correct signal to the compressor to get it to run. It's fairly easy to replace if you would like to attempt it yourself. I can send a diagram if you would like to see how it's done.
That high ohm reading kind of sounds like low freon pressure- I'm sure someone has checked pressure levels though right?
Here is what toyota publishes on replacing the amplifier:
Here is the note on the airbag:
If there is a bad circuit in the amplifier the problem would be intermittent, but typically you will see a b1479 trouble code when the amplifier isn't working.- not always though.
So the ohm reading on the pressure switch was with the engine off, that could be normal then I guess, but it still wouldn't hurt to replace the pressure switch if it is sticking high light that.
