Can anybody recomend a good A/C mech. in the southern Denver area? I would really appreciate it.

The 91 came with R-12 from the factory. If I was more then one can low I would convert to 134a. If your car has allready been converted, the fittings will be diferant then the ones for r12. Any shop that does AC work can tell you if the fittings are old or new. The old r12 have a thread on them. 134a have no threads on them. They are more of a quick conect . You can get a conversion kit for around $40.00. Just make sure to have the system vacumed down before converting and adding the 134a. If you have any r12 in the system some shops will vacum the system down for free just so they can recover and resell the r12.

Thanks for the reply and help! Where can I buy a conversion kit for $40?

My AC blows warm, so I would like to recharge the system. How can I tell if I already have R-134A? I just bought the vehicle. Thanks
