Factory fill was R12, not R134a uless the system was retrofitted.

If it's not lack of R12/R134, it's electrical. Is the compressor clutch operational? Bad climate control switches? Break out your service manual, volt ohm meter and start digging.

If it is leakage, this is better left to a pro. There are way too many places that the system could be leaking and finding it will require a partial re-fill (a vacuum pump as a minimum), a leak detector and a lot of patience.

If it was retrofitted previously then I would suspect a leak, most common source is a faulty seal... and, if you are a wee bit uncomfortable tackling this type of task then I strongly suggest you take paulo's advice ;)

Whatever you do, for the love of God, do NOT use a Wal-Mart leak sealer kit. And please, get it professionally done. Under or over charging a system by even a few ounces can seriously damage it. DIY kits are garbage, IMO.

I'll second this. A/C systems are one place where there's a definite right and wrong way to do it.

The right way is within the realm of a more advanced DIY. But it takes a large cash outlay to get the proper equpiment to do it right. Having a through understanding of how an A/C system works is a MUST.

I know......I spent close to $500 just on tools to repair the A/C system in my Chevrolet Lumina. This was ON TOP of the $1225 I paid to a shop that I thought was reputable (been in business as long as my Pop's shop...+40 years and I knew the guy). Turned out to be a hack grease monkey that had no idea of how A/C systems operated and couldn't fix my lack of cooling problem. The car was in and out of this shop over a six month time period.

I got it repaired and running a constant 40F in 90F degree ambient temps over a weekend :thumbsup:

I highly recommend this forum for anyone attempting an A/C DIY. It's a great place even for the casual observer:
