Been having heater blower issues with my '86 GL Three Door. I've been through just about every blower troubleshooting thread on here and haven't solved the issue, so figured I'd ask.
The blower has always been sort of intermittent, as in it would take turning it on/off and cycling the speed switch a bit to get to start (only on cold starts, once it was going it wouldn't stop for the rest of the trip). Finally it's decided to not turn on at all.
I started by checking the relay, and it is actuating (as in I can feel it click when I turn the switches on/off). I have since replaced the control switch (one with all the vacuum lines running out the back) as my old one was crumbling. I have power to that switch, and I'm assuming to the relay since it's working. Also, the under dash "fan" fuse is alright. I dug deeper, and ended up replacing the fan resistor, as a few of the coils were broken. That didn't help. On a last ditch effort I just picked up a new blower motor, and after plugging it in, it still wouldn't work.
So, where to look next? I think they only fuses/relays associated with this motor are the under dash relay and fuse in the panel, am I missing one? Last time I checked, I didn't have power to the speed selector switch, should I? And finally, I can't seem to find a powered lead on the harness for either the blower or resistor, should I?
Thanks in advance. I've searched this forum for the past few weeks to try and resolve this issue and still haven't figured it out.
