i assume taking the pressure swithc out will release all of the gas?
are the two to the right of the engine bay that you circled ok to remove and inspect or will i need to have the replacement part ready, im not really sure what to expect as ive never fiddled with air con before!
Is there a way to quickly bypass the sensors to test?
Yes i think it will release all the pressure , try finding the connector first
then start car turn on ac then go and wiggle connector to see if compressor
engages. you can safely remove the circled items as these are electrical coils ,
check for break in the coil.
its a real shame as the car runs really well apart from this, im loathed to start shelling money out on air con as it would probably be a never ending pit!
