Weird Blower and A/C control

[ihiryu]

So today I had the A/C running at full blast (as usual) I made a stop at a realty, went inside for a few minutes, came out and the blower motor stopped working. I kept fiddling with the control unit (switching it 0-4) and it eventually came on. Was good to go, went to another stop came out same thing.

 

So I take a look at about four different houses, and the blower motor seemed good. Got onto the highway then the blower motor stopped for a second and came back on.

 

So the problem is definitely intermediate, but I'd like to remedy the problem before it gets worse.

 

I did some searching and don't think the issue with my A/C resistor since mode 4 doesn't work when it cuts out (resistor reduces power to the blower motor for the speed).

Check the wiring grounds for the blower motor.

John,

 

Thanks for the reply. I'm looking at the schematic in my Chilton manual. From what I see, the blower motor gets power supplied from the A/C relay, and the ground is supplied from the A/C resistor, but the resistor is connected to the fan switch and there is one ground there.

 

Would it be safe to say that is the correct ground I'll be looking at?

So I think I found some more stuff, there's a few things just kinda there, and my defroster doesn't work. The heater core hoses are there, and the vacuum space ship thing is there, so I'm starting to think it's the cabling. I haven't been able to find a diagram of it, even in the FSM. Any help with a pic?
