Hi all,

Earlier in the year the heater on my 89 Turbo wasn't working. I switched between modes and on recic it started working. Now that the summer is approaching, the a/c will only blow air ( not cool) in all settings and temperatures. The heat is also no longer working. It won't blow hot air.

Any idea why this may be happening?

Thank you.

You could try switching off the battery for 10 mins to reset the cpu.
Flying spares will rent out a test box I believe.

Hi Jean,
A few years ago I had problems with the battery dying, so I have started killing the battery switch every time the car is not in use I had it serviced recently but they didn't check the a/c. I can try that but I switch off the battery regularly so not sure that would help.

Sounds like AC Relay is blown to me - if compressor doesnt engage and run while in AC mode check Relay
