-27 the other night and my truck did not seem too warm 10 minute down the road so I found I have to give my heater motor a swat to get it started,,checked connections and they seem ok. I took another heater motor out of a 94 Ford F150 today,,it looks similar and without installing it i plugged it into my heater connection and it worked..the screws for installation won't line up by the looks of it but will it work fine?..has anyone else run into this..I also grabbed the rheostat. Will I have any problems? There is a severe shortage of 80's vintage iron locally.
thanks
I would imagine you'd be OK... the speed control is located in the heater core (and A/C if equipped) box, the fan motor is just as 12V motor with a squirrel cage fan on it.
If you can get it physically installed and plugged in, you should be fine....
As far as the motor, 87 up by the parts listing, but if you can at least get a few screws in and have it seal, you should be fine. The resistor wont matter, but keep it for a spare.
Thunder Bay Ontario is on the top of Lake Superior,,about 320 miles north of Minneapolis. All temps are celcius however we have only seen a few cold days,,this is the warmest winter I have ever experienced here...When I first moved here 30 years ago the average temperature for the city during February was -28 celcius,,so ya we had plenty of -40,,was down the northshore a couple hundred miles one night,,,picked up a guy with a frozen vehicle,,,,temp was -55 now that's stinking cold!
Change a spring body on a semi trailer in that weather on a remote ice road, hand bomb all the u-bolts,wheels off and on with only the howling of the wind and wolves for company..gotta love the great white north.
Just as a point of reference... a few years ago, I purchased a replacement motor @ Advance Auto Parts for ~$25 with a lifetime warranty. It performed well for 3 or 4 years and then started squealing. It was replaced @ no charge.
Slightly off subject, but to help others with blower motor problems... if it squeals, likely it is slowing down and drawing more amperage which will soon burn up the resistor which controlls blower speed. When you remove the blower motor, reach your hand in the duct work and remove all leaves, rat nests, etc. This will help prevent future fire as the resistor, which resides in the air stream of the duct work, get hot and can ignite the debris. [Been there, done that!]
Also, it is always a good idea to disconnect the negative battery cable before doing any electrical work to prevent shorting.
My motor never made any noise. I know what you mean as I have heard the various moans, squeals and rattles of a failing heater motor. Gotta love the location of these motors,,guess the engineers were out to lunch and location was left up to plant employee
thanks
