yerpastor Posted December 1, 2020 Share Posted December 1, 2020 (edited) Looking at buying an 89 Reatta. Seller started car and sent me a picture of Dash and ECC. Message "Climate Control Problem Detected/ Very Low A/C Refrigerant/ AC Compressor Disengaged to Prevent Damage/ Service Check Required" I understand the AC may need recharged, based on the message. Could it be anything else? Thanks Edited December 1, 2020 by yerpastor Link to comment Share on other sites More sharing options...
Ronnie Posted December 1, 2020 Share Posted December 1, 2020 Welcome to the forum! The low side pressure switch is telling the computer the Freon pressure is too low. The reason is usually because the Freon is low but it could be anything from a bad compressor to a cracked line or even something simple like a low side pressure switch. I would let the seller fix it before buying. AC repairs can get very expensive. Link to comment Share on other sites More sharing options...
yerpastor Posted December 2, 2020 Topic Author Share Posted December 2, 2020 (edited) Thanks for the warm welcome! Glad to be here! I've wanted a Reatta since the first time I saw one, 19 years ago. Update: Spoke with the Owner. He doesn't believe it to be the Compressor. Says when he turns AC on the Compressor kicks on, but then kicks off and gives the Error Message. He also says there is pressure in the line. I asked him to recharge the system and see if that doesn't help.

DAVES89 Posted December 2, 2020 Share Posted December 2, 2020 One A/C sensor that is often overlooked is the one down at the rack. You may want to jumper that to bypass and see if the A/C then works. Link to comment Share on other sites More sharing options...
RemSteele Posted May 21, 2021 Share Posted May 21, 2021 Team this seems like it is my current problem area. The system has 70 PSI. The low pressure switch is working but the compressor will not turn on. If we jump the compressor it will turn on. Your thoughts.

RemSteele Posted May 21, 2021 Share Posted May 21, 2021 Thanks for the quick reply. Will forward this over to my mechanic. Good weekend, RJ Link to comment Share on other sites More sharing options...
Ronnie Posted May 21, 2021 Share Posted May 21, 2021 Sounds like I'm doing the legwork for your mechanic that apparently knows nothing about a Reatta. 2 1 Link to comment Share on other sites More sharing options...
Padgett Posted May 21, 2021 Share Posted May 21, 2021 Is easy. With that error figure a $1000 repair. Act accordingly. Link to comment Share on other sites More sharing options...
RemSteele Posted May 24, 2021 Share Posted May 24, 2021 Well it turns out it was low and a little over a 1lb later the system is working and cooling the car. Well I'll have to see, it was 93 in NJ yesterday and 63 today. A couple of things: Does not blow out of the dash vents? Only on the floor and defrost. Compressor is leaking. Price quote for a new compressor $550? Any advise would be great, Thanks, RJ Link to comment Share on other sites More sharing options...
Padgett Posted May 24, 2021 Share Posted May 24, 2021 " Price quote for a new compressor $550? " about right for a professional, total job around $800-$1000. DIY is less. "Does not blow out of the dash vents?" Probably a stuck blend door. Rod is above gas pedal. Link to comment Share on other sites More sharing options...
2seater Posted May 25, 2021 Share Posted May 25, 2021 Check your vacuum feed to the climate controller. Vacuum comes from the block on top of the inlet manifold, specifically the hose that runs toward the rear which connects to a sort of tee shaped fitting which is a check valve. One way from the tee (drivers side) powers the cruise control and the opposite towards the passengers side supplies the HVAC controller. It is an 1/8" diameter plastic line which could be melted or damaged. It connects to the center port on the bottom of the HVAC controller which stands upright forward of the glove box against the right side footwell kick panel. Default with no vacuum is out the defrost. Link to comment Share on other sites More sharing options...
