I'm having troubles with my blower motor only working in the highest setting and off. in between settings 1,2,3 are not working. Tomorrow I will go to the library and look at the wiring diagram to find out which relay(s) are stuck. We had a cold snap up here in Seattle and I think the mechanical contacts portion of the FAN BLOWER RELAY(s) is stuck. I'm not sure if there are multiple relay(s) or where they are located.(probably near the interior fuse box). After I locate them, I'll pull them out one by one and jiggle them around to see if I can unfreeze them. They're old 12years+ so I'll probably end up replacing the relay. $40. You may want to check your Fan Blower Relay before dolling out the $100+ for a new Blower Motor, not to mention installing that puppy up against the fire wall. I think it's buried pretty good up in the dash. Your fan motor would not work at all if the fuse was blown. Intermittant failure points to a possible intermittant mechanical failure in a relay $, or worse, mechanical failure in the blower motor $$$. Anyway good luck!

The blower intermittently quits on your 2000 Eddie Bauer Explorer and has finally quit for good is this the blower motor resistor or blower control module or switch?

It could be the blower itself as well. The first thing I would do is find the wattage of the blower (dc, I assume.) and connect the ground. Is there power to the unit?

Blower resistor relay on a 1988 cadillac?

What model? This probably has electronic Climate control,therefore there isn't a Blower resistor. The blower is controlled by a Blower Motor Module...its mounted on the HVAC case under the hood near/next to the blower motor.


The blower fan for the heatAC on your Intrigue comes on by itself when the car is off What is the cause of this?

If your blower motor is either not turning itself off, or randomly turning itself on with the ignition off (and you have auto climate control), the problem is the blower control module. Located directly behind the blower motor, it takes information from the climate control, and is in charge of turning the blower on/off. To replace the blower control module, remove the splash shield under the passenger side dash (there's 3 plastic retainers hold it in place). The blower control module is located behind the blower motor, and is held in with 3 bolts. The 2 rearmost bolts (by the firewall) only need to be loosened, and the front one removed. The entire unit rotates down and can then be replaced.

Where is the heater fan relay for a 993 Mercedes Benz 300 e and how do you fix it?

The blower motor control unit is located on the back of the blower motor. 1. Check fuse. 2. Turn on heat and check for voltage at blower motor. Found voltage replace blower. 3. Check for supply power from the fuse on the red wire going to the blower control unit. 4. Check for a good ground on the black wire on the control unit. 5. Check for control power on the yellow wire from the climate control unit. When you select a fan speed (or the unit selects a speed in auto mode) a voltage that ranges from .4 - 9 volts is sent down the yellow wire to the blower motor control unit. 6. If all these checks are good than change the blower motor control unit. Hope this helps.

Your blower motor relay went bad. You may also need to replace either the blower motor or one of the climate control sensors. If your blower motor squeals or makes a scraping sound it is going bad and will damage the blower motor relay. JQ
