Non AC blower motor Relay
Hey guys long time reader... 1st post.
I have read over the posts about this & all I can find are A/C setups. I have a 1970 c10 (non AC) that has had the wiring "rearanged". The wiring inside the truck is intact & I have a new fan switch. I know the resistor is inside the heater box. My question is where is the relay on a Non AC truck? There is, what appears to be a relay, above the fan motor on the engine side of the firewall; with a gorund tab screwed to the firewall and 3 wire connectors (labled L, B, & S). Is this my fan relay? If so how is it wired? I have one orange wire coming from the resistor through the firewall. Does this connect to the fan motor or a relay? P.S. Pics are great, and I am color blind; so wire color may be hit or miss.. I know it's alot of questions.. Thanks in advance. Smitz |

There isn't a relay on non A/C trucks. The orange wire connects directly to the blower motor. LockDoc |

Cool. Thanks Lockdoc, for the quick reply. I dont know what that relay is for but if it is not for my fan I will not worry about it right now.
One more issue.. When I move the fan switch, I get 12v at high position, nothing on the other positions. Is this the resistor? |

I would think so unless your new switch is faulty. There are 2 wire coils on the resistor board, see if one of them is broken. Gently pry the wiring plug off with a small screw driver, working from side to side. It takes a 5/16 nut driver to remove the two hex head screws Leon. |

I thank you guys for the prompt replys! Whats the best source for the fan & motor, on the cheap? |
