Electrical (Yeah..what's new)
 

The fuse blew out for my heater switch that is wired separately from the harness. I replaced it. Worked fine.

My fan switch (yes, also wired separately) had stopped working. I found that the power wire had been "damaged" to say the least. I completely replaced that wire.

The fans work, but when I flipped the heater switch, the fans turned on even higher. Before the heater used to kick my ass. Now it barely blows anything out. Nothing is different than it was before other than the brand new wires. Any suggestions as to why this would act weird? Thanks guys!

In my 93' there's a relay (or a seperate relay) for full fan, compared to the first 3 settings.

Does your fan get louder on the different settings?
Seperate fuse for the relay (or 2nd relay) maybe?
