runt Posted September 2, 2003 Report Share Posted September 2, 2003 Ok.....this isn't for me. But I was talking to a kid who owns a Regal with a 3.1. Nice car if I don't add. Anyway, he did the conversion from R12 to R134a (he didn't say why, was just telling me that he did) and he says that his check engine light is now on and it never has been before. I don't know how to read codes but I did tell him to go do Autozone and see what they say. He also told me that just before he did that, his car was involved in a small wreck. Nothing serious, just kinda put a few dents in the door and some paint loss. He asked me if the car was hit hard enough would that have something to do with the light comming on. I really don't know, so anything? Thanks for your help!! Quote Link to comment Share on other sites More sharing options...
PaPaPooh Posted September 2, 2003 Report Share Posted September 2, 2003 he could have just converted it with out vaccing the r-12 out thats bad bad might want to ask him if he had it vacced or made sure there was no r-12 in it? does it blow cold air? im not sure if it would kick the ses or ce on or not anyone?

I'm with PaPaPooh, was it properly evacuated? What year Regal? If it's OBDI, you can scan at home REALLY easy. If the two refridgerents mixed, there's a good possiblity that the AC Pressure Sensor is tweaking out. It's located on the high pressure line and that could explain the Service Engine Light. Bottom Line: scan the system and figure out what circuit is flippin' out on him. Get back to us when he gets that accomplished. - Erik Quote Link to comment Share on other sites More sharing options...
luminator94 Posted September 2, 2003 Report Share Posted September 2, 2003 Yeah, I'm with the other two. If there's R12 and 134-A mixed together, it could be confusing the whole HVAC system, thus throwing a SES code. Aaron Quote Link to comment Share on other sites More sharing options...
runt Posted September 2, 2003 Author Report Share Posted September 2, 2003 Alright, I'll be keeping that in mind. Hopefully I'll be seeing the kid soon and the next time that I do I will be damn sure to ask him. Oh, btw, it's a 92 regal. Quote Link to comment Share on other sites More sharing options...
Slade901 Posted September 2, 2003 Report Share Posted September 2, 2003 Well, does the Engine Light still ON if he is not using the AC? If it is a 12 cavities ALDL, you might be able to get the SES code if you jump A and B cavities. Quote Link to comment Share on other sites More sharing options...
H.P.Productions Posted September 2, 2003 Report Share Posted September 2, 2003 I converted my 3.1 GP to 134a and I have the same check engine lighte prolbem......... but it doesnt put out any codes......but I dont have a miss and no overheating or anything so it doesnt bother me...... only thing close to a problem Ive had is.....I put in 2 and almost another half cans of 134a so you can only leave the ac on for a few minutes at a time or it will freeze you to death......but exept for getting way too cold I havent had any problems from the conversion Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted September 2, 2003 Report Share Posted September 2, 2003 I converted my 3.1 GP to 134a and I have the same check engine lighte prolbem.........but it doesnt put out any codes... Are you sure? Cause' that's not right... The OBD system should always give you a code(s) reqardless of an error or not. If no errors, the SES light should flash code #12. If errors stored, those will flash after three cycles of code #12. Oh, btw, it's a 92 regal Like Slade901 sayed, you can ground the system and read the codes yourself. All you need is a test wire or even a paperclip. The paperclip trick always gets the ricers... - Erik Quote Link to comment Share on other sites More sharing options...
89oldscutlass Posted September 5, 2003 Report Share Posted September 5, 2003 I switched mine over to the 134 and my a/c didnt last long till the pressure switch went bad. Even doing everything right I dont think our a/c pump likes the 134. I want my r12 back just dont want to pay the big bucks for it per pound. I think its 60 bucks a pound here which is one can.

Bolt_Crank Posted September 5, 2003 Report Share Posted September 5, 2003 my r12 is still factory fresh, lol, I don't think the previous owner used his A/C very much... Quote Link to comment Share on other sites More sharing options...
91GranSport Posted September 5, 2003 Report Share Posted September 5, 2003 Funny, I never knew that if you're running low on A/C refrigerant that your SES light goes on. My system uses R-12 and prior to recharging it, it was very low and my SES lgiht never lit up. Thankfully, since I owned my car the SES light never lit up.

91GranSport Posted September 5, 2003 Report Share Posted September 5, 2003 Nope, my lights up for 2 seconds when I start the engine. It also flashes quickly when I turn the ignition switch on "run" but not "start". Funny, I never knew that if you're running low on A/C refrigerant that your SES light goes on.

91GranSport Posted September 8, 2003 Report Share Posted September 8, 2003 Hola! $25.00/can for R-12? I used RedTek Refrigerant and it's colder than R-12, compatible with both R-12 and R-134a, and it has built in compressor oil. I had my done for free but if I were to purchase RedTek Refrigerant it only costs $9.00/can and that's in Canadian currency! hey hey hey.... U want to just put r-12 back in?

91GranSport Posted September 11, 2003 Report Share Posted September 11, 2003 I'm not trying to dis you dude, I'm just thinking that's quite a hefty price. Mind you, I don't know how much R-12 is now a days, but if you're living in Canada then it's pretty much impossible to order it. I guess it's good to hang on to those cans, if someone who insists on having R-12 needs them, then you can make some decent cash. alright..... that work for ya.... thats coolIm just putting it out there so if people need it... they know that they dont have to pay up the ass for it... thats all.. later joe Quote Link to comment Share on other sites More sharing options...
91GranSport Posted September 11, 2003 Report Share Posted September 11, 2003 I had a mechanic order it for me. I don't know who the manufacturer is though. Here in Canada you can't order that shit unless you've got an A/C license, and that isn't something you simply write a test to get. Yes, RedTek is compatible with both R-12 and R-134a, it has it's own compressor lubricant and it's damn cold. It's propane based, so you better make sure your system isn't leaking. Or, if it has a slight leak like mine, make sure that the leak isn't anywhere near the exhaust manifolds. where can I get this RedTek Refrigerant? and by compatible, you mean I can just shoot it into a R-12 line or R-134a with no problems?

MaroonRegal Posted September 11, 2003 Report Share Posted September 11, 2003 When I did the conversion in the Cougar, I never had a problem, I'm glad I read this post, I probably woulda tried it. (I might have R134A anyway, the Regal's a '96) Quote Link to comment Share on other sites More sharing options...
runt Posted September 14, 2003 Author Report Share Posted September 14, 2003 Ok...quick update. I FINALLY found the kid and asked him about the coolant stuff...and before I could even finish, he told me that the car is gone. I guess he got T-boned from some lady in a T-Bird (kinda ironic, don't ya think?) I guess she was moving pretty good and the car just isn't worth it to get it fixed, it would raise his insurance rates too much or something (I think he's had a wreck before this, but even tho it was her fault, it would still mess with his insurance) but I just wanted to tell everyone thanks for their help!!!

BC Posted September 14, 2003 Report Share Posted September 14, 2003 When switching from R-12 to 134a you should remove all the oil from the system, (A/C not engine). Usually having to pull the compressor and dumping out the oil, and blowing dry nitrogen through the piping to remove the rest. What they don't tell you is there is a special oil for 134a. 134a and r-12 oil don't work well together, and can cause multiple problems.
