I'm deep, deep into replacing all the A/C components on my '83 SC...barrier hoses, evaporator, both condenser, etc..etc... and just finished the retroaire evaporator fan upgrade. It's been running good for a few days and all of a sudden...bupkiss.

Checked all the fuses under the hood, swapped relays, checked fuses in the back...nada. Using my voltage meter I get 3.6 or so volts at the fan power wire. Is is normal? Can I troubleshoot a bad switch by just jumping power over to one of the fan speed wire (low/med/hi) or should I be using a 12 volt source to see if the fan motor is okay? Did I mention it's all brand spanking new?

Thanks,

Dean
