Need some help please?

 

My air con does not get cold so first things first a re gas. The Toyota dealer said it’s full of gas with no leaks compressor working fine but no cold air.

 

Need to replace the low pressure switch and the orifice pipe "That is what the book said" Didn’t fill me with much confidence just referred to the "book"

 

Any body else suffered from this problem and in principle would that make sense

I have exactly the same problem.

 

I had a brand new compressor fitted and the system regassed and tested for leaks. I ocassionally get some cold air but not very often.

 

It tends to work on colder days which made me think it might be something to do with the Solar Sensor, or the internal cabin air sensor???

 

TBH I dont really have a clue. Will check a few things over the weekend and report back. I downloaded a copy of the A/C-Heater System section from the workshop manual which includes a diagnostic and testing section. I will go through these and see if they help.

 

If you have discovered anything please PM me or for teh benefit of others post it here.
