my ac/heater blower isnt working.
I have a 92 LS power everything (except locks)
i took it out of my teg and i tried benching it not sure if i did it right but i wired my power (from the blower motor++) and - on the blower motors chasis to the ground on my battery and nothing happened.
other things to take note of:
i replaced the resistor a few months back and its still in tact.
no power at all 1-4.
is the motor simply dead or is there something wrong with the wiring?
just want to have my defrosters and heater running again.
any and all help is appreciated.
Yeah I think something’s wrong with the plug only get power from 1 part of the blower motors double positive. I had it working than I out it back in th car and after I turn the car off it topped working again. At least I know the blower works.

Blower motor double positive???
The blower motor should have only two leads going to it, a 12V+, [hot in run and start] and the ground from the blower resistor. 94
Well I have power at one lead so that makes sense the other is negative but i swear on my blower it says + + my resistors work but it works when I took it out but when I started the car two more times it stopped working.
Do you still have power on the one lead, [blue/white] at the plug, if so, with the plug plugged into the blower motor and the ign. switch on, use a jumper lead, [scrap piece of wire] to supply a ground directly to the blue/black lead, just stuff the bare end of your jumper lead into the back of the blower plug with the blue/black lead and touch the other end of the jumper to any ground point. 94
i was having the same problems last winter when i bought my 92 da. i just finally said f+ck it went to the scrap yard found a blower motor and hard wired it with a toggle…it might only turn on high but at least i have heat and can see outta the windows haha.
thats because its a fan! if you run power through it one way, its spins one way, run power through the opposite way, it spins in reverse. right by those + signs should be arrows. that is the direction the fan spins when you send a positive signal through that terminal.
