I was looking at my blower motor for my heater/AC today, to see if I could get it working.. oh boy this is fun.

I started by replacting the relay thats under the hood, nothing. So, I bought a new switch, hooked that up and nothing.

So, out came the test lights and wires.

First, I wired the blower motor directly to the battery and it works. Ok...

So, I tested for power after the relay, no power.. I tested for ground, no ground either.

I tested for power before the relay, it has power. But, there is no ground. There are supposed to be 5 prongs?? on the relay, and obviously 5 holes?? for those prongs to go in.. one of those holes has no wire in it, so I am thinking there is suppsosed to be a ground there..

So, I directly grounded the blower motor and tried to work it with the relay plugged in, nothing.. I am assuming I had nothing because there is no ground for the relay.

Does any of this sound right? I can take a picture of the relay and stuff if need be to help understand better..

I have it hard wired right now, directly to the battery with a switch on the + wire.. because I need something pretty bad..

Suggestions?

 

maybe your relay is bad...rare for the relay to burn out but from what youve said here sounds like your problem...
