Ok I think this threas has diverced into two subjects. I am at a stopping point with trying to diagnose why the AC isn't getting cold. I checked and it has been converted to R134. Everything comes on fans, AC clutch..I tried to fill it with coolant and it didn't even take 1/3 of the can..I have driven it around for 30 miutes and the lines get cold. coming from the firewall the line coming into the evaporator is cold and all the other lines excpet for the ones coming directly from the compressor...Any other suggestions???Thanks

Where exactly would that be located?? behind the dash some where??

So what should I look at trying next..,Take it to the shop and check the pressures on both sides since it didn't take hardly any coolant...

OK so the system seems to be full. I tried to refill with R-134 and it didn't even take 1/3 of the can...Could the expansion valve have anything to do with it???

Mine has the red and blue caps on the fittings but other stickers indicating R134. What should I do?? Bite the bullet and try to recharge with R134???

the pipes are not freezing but they are cold..Is there a visual way to verify if it has been converted to R134?? Reason I would like to know before I add coolant to it..

I am going to check everything this afternoon ( pressure and if the evaporator pipe is cold) I willpost the results tonight. Iw ould really love to solve this problem myself and not have to take it to the shop..Thanks for the input guys..

Alright I finally got the miss figured out in the engine but I have another question. 91 Legacy 2.2L. When I turn the A/C the clutch engages and everything sounds ok. The down side is that it nevers get cold. I checked the high and low side pressure and it seems ok as well...Expansion valve or something stuck?? Where can I begin to look?? Maybe even compressor issues??? Once again thanks guys for any input...

1991 Legacy wagon 2.2L When I start it the thing starts missing like crazy, the check engine light comes on. After 5 or 10 minutes it quits adn runs great..Any ideas???
