Hi,

I last year i bought this car and the A/C was not working. So i checked the pressure on low side valve and saw that there was no coolent in it. At this stage it had R12 valve. I put a r134 valve on it and filled with r134 coolent it was working fine. But now it doesn't cool at all. The compressor start but doesn't cool. I checked pressure and it is in 70psi. suggest me what shud i do to get it working.

Regards,
Jimmy

When you switch to R134A you should also change all the seals and use a different oil.

You most likely have a leak somewhere.

Best advice it to take to an AC shop and have it repaired, or change all the seals, but it is illegal to vent 134A to atmosphere.
