I checked as far as I could and for the life of me cannot find he Low presure service valve for the A/C. The manual doesn't reference the R134 system and the pictures show it on the compessor which I cannot locate on my unit.

Help please?

Thanks

 

under pass side intake tube, should be a low side there
on the dryer should be high side

 

I see the high side on the dryer but cannot find the low. I checked under the tube but came up empty. I will check again and see. There is so much there it may be out of my sight.

 

i am going off of my 82 which should be the same as yours. BTW its not all that obvious under there. it is kinda deep down in there to be honest.
pull the intake tube and try to follow the line from the dryer back up there, or back from when they enter the firewall

 

On a GTS it is under the plastic cowl - next to the wiper motor

Now that I have regained my composure, I can thank you.

It would have taken me a month to find that at this rate. Last place I would have thought to look.

A million thanks.. Have a good weekend.
