Question about 1980 Cadillac Eldorado
The digital readout works intermittantly and when the digits are not illuminated, you cannot control the heater temp and fan. I went through the wiring with no sucess. Could the ecm affect this?
I had a similar problem. I replaced the control head on the dashboard. that seemed to fix it.
you may also want to check the power amplifier located on top of the airbox off the firewall. sometimes this part can be an underlying issue. I had to replace that too.
