Blower not working

[MiniMe]

Recently bought a 91 explorer. The blower motor quit working. Well at first it would work when I banged on the dash but now has completely stopped. My first thought was bad connection at switch. I pulled the connector off the fan switch. I jumped yellow (keyed hot)and org/blk (fan high), blower did not come on. I ohmed my blower motor and got .8 ohms. I pulled off a connector towards bottom of blower motor with org/blk and pink wire. I get power to org/blk wire with test light hooked to ground.

Also noticed when I bought the explorer the blower would stay on when key is off. I have not messed with wiring. I just tried to remember to turn blower off and keep a set of jumper cables when I forget.

Any Ideas?

Sorry, been a while since you posted...but if you have power at the connector then the blower motor is probably fried. I had to change mine out last year for the same reason...thought it was the resistor in the firewall but it usually works on high only when that is the case...so if it is completely off then you might want to make a trip to the junkyard to get a new fan...

You can test them by hot wiring the motor direct to a dc source...like on your battery before you put it in...the junkyard where I got mine actually tested it for me...since they do have batteries galore!
