The blower in my 99 Safari stopped working on all settings the other day. Before this, only the middle 2 speed settings would work, and then one day, nothing on any setting. So, I removed the switch which looked very worn, and replaced it with a new one. Still nothing. I then pulled the motor, thinking it was bad. After removing it, I noticed the wheel spins relatively freely, so I grabbed a couple jumper wires and connected it to the battery. The motor functions fine. I'm aware of the resistor going bad and causing only the high speed setting to work, so I didn't think that was the issue given no settings work at all. Now that I've checked everything else, including fuses and relays, I decide to remove the connector from the resistor. In jostling the connector, the motor kicked on in High. Bingo, or so I thought. I turned off the key, and went to remove the resistor, and found that the motor was still going with key off and out... I disconnected the connector from the resistor, and found that the far left (large red wire) prong is quite charred. I then removed the resistor and found that on the board, the line leading to the big red wire had a bubble in it, so I went and picked up a new resistor. Before connecting the resistor, I grabbed my multimeter, and found that a constant 12v is going to the red wire in the connector. I pulled the AC relay in the underhood fuse panel, and no change, so then I pulled the MAXI 30 amp fuse, and the reading dropped to 0. So, in conclusion, I need to figure out why the power isn't being cut off when the ignition is off...
