Problem with my A/C - JackoliciousLegs - 04-27-2004

Quote:explain please. what charge? electrical charge? how do i check the ac clutch?
Quote:unscrew one of the caps on the AC line it looks like a valve stem and push it and see if if anything comes out
Quote:it blew air... car was off and cold.. and i pushed the little valve and psshhht... air for like 2 secs. Then i stopped. What does this mean?

It's going to suck if you need to have your system recharged - most places won't mess with freon.
Edit - The difference between a cold AC and warm air can be a couple PSI of coolant - the AC at our old house had a slow leak in it. Every year, we had to pay about $50 to have ~2 PSI of coolant put into the system (I think it held 30 something total) - without those couple PSI it would blow warm air, but with it it was ice cold all year. Good luck.

Who needs AC?

^Agreed. Be a man and remove it. I'll help.

Black on black leather... we'll see how much it costs first. Then if it's horrendously expensive, I might remove it. For now:
Assuming i'm out of refrigerant:
What's the avg. price difference between r12 and r134a? Is it worth it or should I just take it to a shop and have them refill it with r12 and get it over with?
- BLINGMW - 04-27-2004
You'll end up paying hundreds for an r-12 charge, and if you've got a slow leak, you'll be doing it again soon. I'd look into an R134 retrofit kit or an r12 replacement. Products like this are supposed to be able to be used in an r12 system http://www.freeze12.com/ without changing anything. The shop across the parking lot here says they've used things like this with excellent results. I'll ask him specifically what brand he's used. And I'm sure plenty of RX7 people have converted to r134a, there are some REALLY cheap kits at autozone and walmart to do it, sometimes they work ok. And I think there are more expensive kits that will work very well, just see what kits people have had success with. Once you've converted or found a cheapo r12 replacement, you won't be throwing hundreds of $$ at it every year, maybe just a few bucks at the start of each summer. This is assuming a leak is the problem, you might be able to test some components and see if they're working right. Not my specialty.

sweating builds character :lol:
- Mike - 04-27-2004
If you plan on keeping the car and want to fix it I'd definitely go with an r134a retrofit kit.
- JackoliciousLegs - 04-27-2004
How can I find the leak? Should I just pay someone to do it?
- JackoliciousLegs - 04-27-2004
Yeah, I'm just going to take it to a shop in NoVa to get it checked. I did a lot of reading on it. I think that's just the best.
- .RJ - 04-27-2004
A shop will need to discharge the system. Then they'll test it by charging it with dye, and running it, and finding hte leak(s). Then they'll replace the worn seals, and fill with R-134.
Probably a few hundred $$$ for the time/labor. R-134 is cheap at least.

It's an R-12 system. They will not recharge it with r134. R134 operates at a higher pressure and is known to blow rx7 a/c systems with great ease. They have a pressurizing device that checks if a leak is present (doesn't check location) that I'll get some shop to do. If there is no leak, then I'll start looking at whether the compressor's gone. If there is one, I'll look into my options then.

Good luck finding a shop that will touch R-12......

Freeze12 is EPA approved.
- .RJ - 04-28-2004
Whats Freeze12?
Oh, why would a system operate at a higher pressure with R-134A over R-12? The pressure differentials of the system are determined by the hardware (compressor, evap, condensor) not the fluid in the system. Either way, the car is nearly 20 years old and a/c seals leak. Its not a 'DIY' job because you'll need equipment to discharge the system and tools to separate the fittings.
- JackoliciousLegs - 04-28-2004
Yeah, I know, that's why i'll take it a shop...
hrug: It just sucks
