My Windstar cruise quit, and after lots of looking it was the "switch" on the brake master cylinder. Only when the switch got very bad did many things quit. It was low voltage that made the cruise not work so if not the master cylinder switch you may have a bad connection in one of the many plugs power runs thru causing a low voltage problem..

My blower motor wont blow


bad fuse,
it can only be 3 things, a voltmeter finds this easy and every time.
bad fuse, bad switch bad, motor.
as we all know that includes all wires and connections, fore ever.
so you can check the blower , 12vdc on high.
if 12v there, and motor is silent the motor is bad or lost its ground.
to check that 100% apply 12vdc to the motor, bingo it works?
so no 12v to motor, must be bad switch, huh? after all the fuses is already checked(with ohm meter not eyes !)
so now i have 12v to the switch and no 12v out. must be a bad switch
easy huh?
ill now look yours up to see if there are other oddities.
alldata.com
ahh , up to 4 blowers, 2 front and 2 rear. fun but the 2 front are in parallel. and bingo, all 4 have there own FUSES !@!!!
forget that its rear and a/c only , what a complex car. no biggy
electrics is my game
i go to page 3 for HVAC, allh the heater, omg 2 relays 1 fan
the switch does NOT power the fan.
the switch only energizes relay 1, the ground relay
this heater relay pulls in and grounds the FAN.
ok 1/2 done.
next relay is Power side blower relay.
it gets 12vdc power from its very own 40Amp, Circuit breaker
the switch also ground this relay, it too energizes and bam
12vdc hits the fan
id bet the fan is good, and shock, no need to pull dash to get it out...
all that , in 5min flat , alldata.com
try it.

ask questions.

1999 Mercury Mountaineer, heater/AC fan no longer blowing


I would check the fan first disconnect the electrical connectors on it and use a pair of home made jumper cables and run it from the battery. If it works move unto relay if it doesn't you've found the culprit.
Next check relay in the fuse box. Coolant tempertant switch(CTS) aka thermal switch and its circuit. CTS is usually located in the water jacket by the t-stat.

No air coming out of the vents


It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.

Heater blower stops working


Hmm, a problem that I have not encountered before. My best guess is that some component within the heater setup is getting overheated and then it shuts off to avoid further damage. If the heater runs each time you start the car and then turns off during your travels, then this might be the case.

Secondly, there are circuit breakers located in the fuse box. These are silver and are about twice the size of a standard fuse. Unlike a standard fuse that blows once and is done, circuit breakers get hot and "trip". After they cool down the connection is made again. Look to see if a circuit breaker (sometimes labeled CB) is in the fuse box and serves the heater. You may want to get a new one.

Heater Fan does not work


Sounds like the fan control knob has shorted out. You can check the fan "blower" relay and fuse in the engine compartment but you need to make sure the control knob is good or you will keep blowing fuses and relays. If your blower fuse and relay are good, then just have the control knob checked and replaced if needed.

Heat /ac fan doesn't work properly


Check the relay for the blower. it may be locked . tap it lightly or jiggle the relay or check with a known good relay.this two circuits may be interconnected. check the light relays as well and fuses.
