Only getting 5V to Windows and blower motor

Postby justin.loehlein » Sun Nov 04, 2018 10:29 am

So, my power windows and blower motor on my 1990 stopped working. They share fuse panel power from the same source. I am only getting 5 volts at the fuse panel for those two spots. Everything else is 12 volts. Any ideas?

The wiring diagram makes it look like the ignition switch is the only thing between the battery and those fuses, but I can't figure out how to get to the wiring at the switch.

Got it. The fusible link under the hood was broken/corroded. What do you all typically do to replace those? Am anticipating the others having issues at some point.

I bought a fuse block from Napa and wired them into that. I had my brother help me since he knows how to read the wiring diagrams in the FSM and I don't.
