1997 f150 ford heat only works on high

Recommended Posts

On my grandsons 1997 ford pick up with a 5.3, the heater gets hot but the blower fan only works when I turn it to high. Control module maybe?? Thanks

On high the blower motor resistor is bypassed. With it working on high the power and ground are good. This leaves the switch and the resistor. My money is on the resistor. 

 

Remove it and ohm out 2 and 3, 2 and 4 then 2 and 1. If you find an open replace the resistor.

The Blower resistor is located near the blower motor. It will have a four wire connector and two 8 or 7 mm screws holding it in place.

    • I never said that at all but my choice of "grill" or "smoker seems to bother you for some reason.   It's OK if you are a little bit jealous of my pellet smoker.....    
    • How does the cold smoke accessory work? I wouldn't fathom doing any this time of year or does it have a built in ice tray to keep foods cool?. If not any grill or smoker would do the trick in the cold. I'm with others,  having room to hang for long smokes works the best. It is a nice concept though.
    • The fatty was good! Got up at 6:30 am Friday morning to put it on the pellet grill.    
    • Ants are just trying to make a livin.
    • Buy an ant moat. Feeder hangs underneath it. Ants can’t cross the water. While I have never used this, I used to put my cup of grape jelly on a small plate, filled with water. Never had a problem with ants. So, in theory, the moat should work just the same.
    • I grease the pole with Mentholatum 
    • Gotta love wings!! Had to see what this reverse searing is about. Pork chops off to the side grabbing natural hardwood smoke then over the heat... tasty. 
    • Did a bunch of wings in the steam pot for 15 minutes yesterday. Let them cool and then brushed with oil and rub. Left uncovered overnight in the fridge. Tonight I grilled them indirectly over some charcoal and apple pellets in the smoker tube. Finished them off over the coals to get them crispy:
    • I'd just take a $20 loss and use the proper stuff your outboard is specified for.    It's just not worth it.   I feel like this falls into one of those "if you have to ask the answer is no" sort of things.
    • I have a half gallon of arctic cat APV oil, and was woundering if this can be used in my oil injected 2 stroke Yamaha 200HPDI? I bought a new sled this winter that requires C-TECH2 oil, so I have a half gallon of 45$ oil just sitting in my garage.
