1999 Mercury Mountaineer Question: blower fan not working
Answer #1patrick mannion from Greg Solow's Engine Room, July 11, 2009, 18:37Master
The blower motor is in the rear of the engine compartment (passenger side). This vehicle also has a blower motor resister (in the engine compartment) that allows for fan speed control that may fail. There is also a fan relay, switch, wiring and fuses in the circuit.
Check the 40 Amp main fuse at the battery area fuse box, the fan control relay is also in this fuse box, 7.5 Amp fuse #2 in the fuse box (I think this fuse box is in the passenger compartment).Check your owner's hand book for the fuse box location and fuse identification.
