My second venture into 700 turbo wagons is a 1990 760 turbo I picked up for $1000. I rebuilt the suspension with new steering rack, ball joints, tie-rod ends, shocks. I converted the rear from nivomat with the IPD conversion kit (it was on sale). It runs beautifully, however the blower control does not function and the AC button flashes continuously. I read that this is an error signal and the blower might be disabled by the system. I tried to follow these instructions to invoke diagnostics mode:
1. shine bright light on solar sensor
2. set blower control to [AUTO]
3. set function control to [vent]
4. depress recirculation switch
5. press and release AC button.
Unfortunately I could not complete this successfully over several tries so I could not get a hint as to exactly what is wrong. All I need right now is the blower so I can get some heat and defrost going. Is there a way to bypass the ECC and operate the heater fan manually? Or, is it simply that the fan doesn't work? All the fuses are intact. I'm hoping for an easy troubleshoot and fix. It's cold outside!
