Blower Motor Issue

Bought a 1995 GA SE with the 3.1 v6 for my daughter to drive to school.
Now with Winter coming on, the blower motor won't run. My kids tell
me the car is posessed, because when they're close to their
destination, the motor will start working. Seems if the car runs for
20-25 min, the motor will kick on. I ran the car in the driveway yesterday
for 20-25 minutes, I can't get the blower motor to kick on.
I replaced the 25 amp fuse, reseated the circuit braker (one in fuse
panel) reseated connectors on back of blower motor (from engine
compartment). Nothing is helping. Motor still dead, at any switch
setting. I'm not sure how to proceed from here.

Any help appreciated,
Jack

replace the motor.

i also have a 95 and just had to replace the switch on the dash, i had no speeds at all. the switch was cracked. the only place to start , the easiest is the switch and go from there.

some of these years had to cut the firewall to get the blower motor out.

I'd try running the blower with a jumper wire from the battery. If it runs then the troubles else where.
