Default Heater Blower motor just quit.

Jumped in this morning and as soon as I urned he key I noticed no fan. Tried all the positions and the only thing I get is what sounds like a faint click when I am leaving the "3" position going to he "4" (high) position.

Murphy must have a special place in his heart for me as he ALWAYS knows when it's best to read his laws.

Perfect timing.

For what i's worth:

Test power at the motor (under hood far passenger side against firewall). Make sure the blower speed switch is on hi when you do this. If you have power, then replace the motor.

Okay, someone cue "The Twilight Zone" music cause I just went out to test the leads and the damn motor is now working just fine.

While I could just be happy with that, this is NOT the time of year to just "go with it" and be left without the blower the next time it decides to go on strike.

Has anyone else had this happen and (eventually) solved the mystery?

I had the same problem on a Ford Probe years ago. The brushes were bad on the motor and it would work when I pounded on the dash board a bit. Eventually it quit working altogether.

The other thing I thought of was the temp: -8 when it would not work. Temps are above zero and it is in the sun now.

Maybe bad bearings/worn armature in the motor itself?

you may have moved something when you went to test it. May have been as simple as a connection issue. Time will tell. Jerry

i had this problem too, connection gets corroded or loose. mine would cut out on bumps...just find the wires "happy place" and secure it till you can fix it "right". try zip ties. maybe clean the leads...be careful housing plastic can get touchy and crack...my big mistake.

Ha,thx!
I was highly desperate not having any available time to order parts to arrive in the cold
temps,so i had no choice but to tear it all apart and do it like i did. To whomever designed
that stupid blower housing on 95 blazers, i put voodoo curse upon them!Putting it together was the stupidest of angles!
