yellowdog Posted June 25, 2014 Share Posted June 25, 2014 Guys,The a/c no longer blows cold. My guess is the coolant has leaked out (will take it next week to the mechanic to confirm). Can I still get the same type of refrigerant oil as was originally in there? If not, what kinds of mods have to be done to accept the newer refrigerants?TIA, yellowdog Link to comment Share on other sites More sharing options...

If you need more than a pound convert to 134a. You can get a conversion kit on-line for a fairly reasonable price. If you mechanic is checking your freon and finds it needs half a charge, don't just dump your charge to the open air. Have your mechanic do your prep for the remaining R12. He will suck your system down from pressure to vacuum and save your R12 to a big can and someone else who needs a few ounces can put it to good use. With that done all you need to do is screw down the adaptor ends, follow the conversion kit instructions and start making ice cubes.Of course if your system has sprung a real leak and not just oozed out as they do with use and time, you will need parts.

Guest TCBucky89 Posted June 25, 2014 Share Posted June 25, 2014 My A/C only blows cold when I have it on RECIRC. When I put it on the lowest cool setting, it blows really hot air!!!! Link to comment Share on other sites More sharing options...

If you're lucky its a vacuum connection to, or the heater controll, if not, you're in for a close up view of the underside of your dash. Link to comment Share on other sites More sharing options...
Guest TCBucky89 Posted June 26, 2014 Share Posted June 26, 2014 Anything special to look for? I will have the center part of the dash out to change the stereo, so I may be able to check out the A/C at that time. Link to comment Share on other sites More sharing options...

Don't forget to check the check valve, then log onto rockauto.com and get yourself a new blue shop manual, sounds like you need one and it will be $47 well spent. They also sell hood struts $22 and sometimes the storage lid strut $17. Don't forget to shop partsgeek.com they sometimes have what others doon't.

Guest TCBucky89 Posted June 27, 2014 Share Posted June 27, 2014 I will check, and double check all these tips and hints. Looking at something more than once is usually a good idea before making any drastic decisions!! Thanks for the help, guys. I really welcome all the input I can get!
