Automatic/Analog Climate Control Conversion


Registered User
Hello everyone,
I have a 1991 and 1993 SC, both are 5-speeds and both have Automatic Climate Controls. I know that Auto Climate Control was not available until the 1991 model year for the Thunderbird, but I was wondering how difficult it would be to swap out my Auto for the analog controls. I realize that 1989-1990 have a different wiring harness than in 1991, and the little cubby in the dash with sliding door was eliminated (due to clearance issues with auto controls) which is why you can’t just install the Auto control in a 1990, but I was hoping I could install the analog controls in my 1991 and 1993 SCs. I want to make my 1991 and 1993 SCs look just like a 1990 and I’d like the climate controls to work.
Thank you very much!

Can't help w/swap details other than to mention the later controls include an additional temp sender - see comment #2 here:
