blower motor resistor?
Where is the blower motor resistor located in a 78 L82 4spd w/ac? If anyone has this information could you please help? Thanks in advance!:cheers:

It sticks down into the A/C box from the top. Looks like a flat football with a wiring plug on top.

'78s, I believe are slightly different, but this should give you a good idea, Pass side near fire wall:

Thanks guys! I believe this may be my problem ( no control of blower ) , had the same problem on my wifes 04 trailblazer and that was it. I would hate to tear all that sh!t apart. I never use the ac or the heat for that matter, don't need the blower randomly turning on though. I will let you know when I tinker with it.:cheers: :cheers:

My 79 fan only worked on Hi-speed, the relay turned out to be bad. Another thing you might check, and it is located just above the resistor in the picture posted, but in my 79.

blower motor resistor
On my 76 when I turn the AC to the highest setting, the blower stops. I have replaced the relay I have checked the blower motor resistor and dont know what the hell Im looking at. Any ideas on why the blower stop when turned to high.

also check ground wire to blower motor......it should be a black wire separate from harness running from blower motor through firewall.
Good Luck |
Trust DWncchs, you will find a 30 amp in line fuse on an orange line someware on the left fender near the M/C. PG.

That's the one. Mine was badly corroded and needed replacing.

I found the orange wire on the left side near the M/C but there is no fuse.
|
Replaced the resistor and still nothing.
|
Also noticed that when the switch is in the off position the blower motor still blows very low. I have replaced the switch.

No orange wire.
