I have this strange A/C problem. I recently relplaced my evaporator and compressor. flushed the system and converted it to R134. Now the A/C works fine at idle but when the engine revs past about 3k the compressor seems to seize up. When I had the system evacuated and had the A/C guy put in oil, could he have put too much oil in and it doesn't want to compress? That is the only think I have been able to come up with. Any other ideas? I need to get this resolved quick, the 7 is my only car with A/C and I am sure it would not be fun driving without it when it gets up to 110.
thanks

 

Like I just told the other guy around here now with the a/c problem, the best way for you to get past all of these probs is to just forget about using your a/c. And like I also told the other guy - no offense, but maybe the FD isn't the car for you if you have issues with the a/c functioning properly. It's a 'everything you need and nothing you don't' track car imo. Check out a BMW or audi if you desire ice-cold a/c at all times when you're driving or look into a different class of sports cars.

 

I forgot the exacts but, somewhere around 3500 the a/c is suppose to shut off, can't remember if it was at WOT or not.

 

First of all, like I said, It is the only one of my 2 cars that even has A/C. I wonder if the '74 REPU had A/C as an option? Second of all, I put a shitload of money and work into my car. If I can help it, I am not going to leave it sitting in the garage for 6 months out of the year because it is over 100 for 18 hours of the day and the A/C is having problems. All I asked was for opinions of what might be wrong. Not your stupid *** remark about why it shouldn't matter if the A/C in my car works. You had better not be saying **** like that unless your 7 is completely stripped down, no A/C, power steering, door panels, passenger seat, radio... Get the idea? Now go away.

 

I don't think that is what my problem is. I think my (new)compressor is actually seizing up because it will almost kill the engine. Then after it drops to idle for a few seconds the compressor will spin up again and I get cold air again. When the rpm's get higher the compressor has a hard time with the speed increase. That is why I think possibly too much oil (which doesn't compress) in the system. Thanks for the idea though, I will look into it and make sure that isn't what is going on.

 

God forbid someone want the car to work properly

 

It does sound like it's the compressor. Maybe the bearings are bad. Did you buy a New one or a rebuilt one? I think if it has to much oil you can just push the valve on the (low side) and let some of it out, if only air comes out then I think it's fine. Basically just push the valve and either air or oil will come out but don't hold me to this, just what I heard.

 

I live in a climate that is just about as hot as the one you live in (FL) and I never use the a/c. A little heat won't kill you little man. Just driving an FD in the first place should help you forget about how hot it is and enjoy driving. I was also sure to put 'no offense' in with what I said to be certain that I wouldn't get crap back from you, but I guess I was wrong. Or maybe you just need to read a little closer. It appears that you're the one making 'stupid *** remarks' i.e. hostility imo, so I think you're the one that needs to go away. The forum doesn't have a place for those who take the offensive. I would think that you would know that by now.

 

God forbid that I would get a response any different at all from a newbie like you.

You couldn't possibly have an FD if you think someone would 'want' it to work. With an FD, you have to 'hope' it will work because it has no remorse for a sobbing and pleading owner. Anyway, I did notice that you don't have an FD (I was right!), but I do compliment your ownership of a Talon. That was my first car (indy red '96).

 

Sorry, but I have been here a while, and I would not be happy if my AC didn't work. Half *** may not be everyone's cup of tea.

 

Let me guess, 18 years old and mommy and daddy paid for your car? Come on, how close am I? As I already stated, I asked a question hoping for ideas as to why my A/C was not working. I was not looking for somebody's opinion on why it shouldn't matter if my car is not fully functional. If you have something meaningful to add to the thread then by all means say it, if not then don't post.
thank-you

Oh, and I relieved a little pressure from the system last night and it seems to run alot longer bofore the problems show up. I guess I will have to get a pressure gauge and check that out. The compressor is new from Mazda, everybody had told me to not get a reman because they usually don't last as long.

 

Get some gauges on it and check the pressures. There are saftey switches in the a/c lines; one for too little pressure and one for too much. It's possible since it was just recharged that it was overfilled and once the revs build up the system overpressurizes and the compressor shuts off until the pressure drops back down.

This wouldn't cause any strange noises though, the compressor would merely cycle on and off.

 

oh god! bring the newbis **** since you don't have a real response. Don't be afraid that a 'newbie' might make a good point.

I am buying an FD and I will want it to work, and it will. WHY?? because I don't have the same passive attitude that you do about hopign it will work, and if it doesn't "well that's just the way RX7's are".
Who cares if I don't have one, that has no bearing on my knowledge of this vehicle, or anyother, nor will you change my mind.
Yes, exactly, I own an equally fragile vehicle as the FD. A lovely AWD crankwalking 95 at that. Every system, every problem, but I'm not gonna sit around and aaccept the fact that something breaks. I fix it. There's absolutely no reason why the man shouldn't expect to have a working a/c all the time.

 

I'll have you know that I spent every penny I had from two years of work at three different jobs (lawnmowing for a local business owner, Bresler's Ice Cream, and Circuit City - salesperson) to be able to finally get the automobile I desired. I don't take handouts from anyone and I know for sure that my parents need to spend their money elsewhere than on material possessions for their children. Oh, you're off on the age by the way - 20 now and 21 next month

I'm also well aware of the nature of posts that should be made on this forum. I've been around here a long time.

Anyway, I guess I'll be the first to say something positive here by saying that it's good to hear that things with your a/c are looking up.

 

All right, so no harm done. Now we can all be friends and get along again. Thanks for the moral support and encouragement with the progress I am making on my A/C

 

Your point seemed to be just along the line of something mightyslash might say, so if you would like to put your point into argument form for me and show me that it is valid and sound, then maybe I'll give you some credit. Oh, and lengthened responses with support do help someone convey their idea more effectively if you didn't catch my drift.

You have to realize that a/c is something most FD owners would consider as unimportant and would still buy the car if it didn't have it in the first place. When you do get your FD though, I hope you'll be concerned with the proper functioning of other areas first before the a/c .

If you think an AWD Talon is as fragile as an FD, you have never worked on an FD before, trust me. Go replace all of the vacuum hoses, pick around at the solenoid rack, and take apart the entire turbocharger system /put it back together with everything working right and then tell me what you think.

Start typing your responses up properly too; you almost remind me of AARotary.

 

1> Good job telling me what others think. And all supra owners are ********, just like all fD owners are such hardcore enthusiast that they think nothing of A/C. I'll just go through 110 degree summer months without. The car is just THAT good

2>You have never worked on the reason mitsu america is known as mitsushitty

3> Continue with the personal attacks; just shows that you have no substance whatsoever, and are only looking for a mudslinging match.
