1990 HVAC Problem - Dashes on display

All,

I am having an issue with my C4's HVAC. The blower fan is permanently on. I have no response from the head when I try to use it normally, and when I tried pulling up the codes none were stored. Has anyone had this issue before?

Thanks in advance!

Pulled the programmer from under the dash and replaced the capacitors. No change.

Finally was able to make the programmer function. Now I have a Code 6 Inside Air Temperature Sensor short. Does anyone know where this is located on a '90?

Have you tried this fix? I had a similar problem with my auto climate control. Take a look at this video. It wasn't hard to do and it did fixed my problem.

The dashes reappeared on the control head. I am able to make it function somewhat by disconnecting and reconnecting the programmer, however, the codes 2, 4, 6, 8, and 10 appear. Looks like I will be trying another programmer.

New (used) programmer arrived today. Installed the new capacitors I had put in the old programmer and connected it to the car. Everything now works as it should.
