QuestionHello!
The question isn't really about a Cadillac but I heard they have the same system... It's a 1980 Pontiac Bonneville Brougham.
The Automatic Climate Control quite working. I already had in the past the selector that burned (twice) so you can't select a mode anymore. Changed it and it worked fine until this summer.
The temperature works... but the fan is always blowing at the same speed (low), whatever you choose (Economy, low, auto, high, bi-lev, def).
The vent working are the right one. When it warms up, air is coming from the lower vent, when cooling, from the top vent, etc...
The only probleme is the fan speed. Is did funny stuff before stoping. (stopped, restarted, one day it was working, the other it wasn't, but now it just stopped.) I check the fuses and the connection to the programmer (somebody told me they ould be corroded)everything was fine.
Thanks in advance.
