Blower Motor Relay?

I started my truck yesterday, and the fan wasn't working. I checked the fuses, and they're all good. When I got home last night, I pulled the "blower motor relay" under the hood to take to the parts store for a replacement. I headed to the store, and, just for the hell of it, tried the fan....and it came on (without the relay installed), but the windshield wipers wouldn't work. The parts store didn't have the relay I needed, and the fan wouldn't come on after leaving the store.

Here are my questions: Are the wipers connected to this relay? And, if so, is my relay still good if the wipers work? Is my fan issue something other than the relay?

Don't know why the blower started working, but are you sure you pulled the correct relay? The blower relay is second from the back (towards the firewall), the wiper/washer run/park relay is second from the front (toward the radiator).

The two circuits are otherwise unrelated as far as the power feeds or the relays go. I would look at the blower motor and speed control resistor if it quits again.

The wiper/washer is fed by fuse 15 (30A) in the power distribution box and fuse 11 (10A) in the under dash fuse panel. The GEM activates the wiper motor and wash pump based on control inputs from the multi-function switch.

I'd bet $1000 i pulled the wrong relay. I'll check that on lunch break. The fan started working about 2 miles before I got home last night, and worked this morning.

Well, I pulled the wrong relay. My windshield wipers work perfectly, but my fan isn't working at all. I need to get it working before wednesday because I'm driving from Houston to Dallas during the middle of the day. Where do I find the resistor, and How do i check it?

as stated before, check the resistor for the blower. If it runs full speed, but not others, it is likely the resistor. Each reduced speed has a different value resistor in circuit.

When it runs, it runs at all speeds, but when it's not running, it doesn't work at any speed. Where is the resistor, and what's the best way to check it?

The resistor is located in the engine compartment on the blower housing . Look for the wiring plug that attaches near the motor bulge. One screw to remove it. look for cracks and broken wires, or test each circuit with an ohmmeter. If this tests good, you may have wiring issues.

My problem turned-out to be pretty easy. I figured I'd post the solution just in case someone finds this thread in a search later on down the road. My fan didn't work at any speed, so I hit it with a hammer and it turned on. I bought a new fan at HiLo for $40+tax, and now I'm back in business!
