Testimonial: "All the fuses are good. I have ordered a new relay; AC Delco. If that does not correct the problem, Where would I be able to find a New Control panel? besides going to the dealer and grabbing my ankles.."

    Budd if after replacing the relay it does not fix it you going to have to ebay.com or amazon.com for bettery prices and by the way you dont need to wait for the new relay to arrive just disconnect one somilar close to it and see if it works do not force nothing just get one similar

    I tried two aftermarket ones from local parts dealers. Neither worked, then i found a airtex replacement. i recently found a AC Delco 15-8794 replacement, and ordered it.

Your new resistor should contain a built in relay. Sounds like that is sticking, swap the new part for another as it could be that you got a bummed replacement.

Disconnect the module and power the motor direct from the battery and see what happens.-----------The problem is the blower motor control module is shorted. This is a common concern these trucks. The blower control module is located next to the blower motor. It has 2 wires that come out of it and goes to the blower motor, it also has a small wire harness going in to the module. If you unplug this module, the blower will stop. You need to replace this module to repair this issue. The module is plug and play, no programing needed.
--------

This module have one plug that goes into the unit and two wires going out of it to the blower motor

with two mounting bolts and two silver plates on the othe side of it.

I would check that the blower motor speed controller under the hood is getting a signal from the climate control. The speed controller will be a lot less expensive and goes more often then the climate control unit in the dash...

You should really test the signal from the climate control to the blower speed control; if I where to try something I would go with the blower motor speed control... it may be called the blower resistor if you call for the part just make sure it matches up with the one you have on the car.

Good luck.

Could be that the switch itself is shorting and allowing power to flow,if you can get to the switch I would use a voltmeter and see if there is voltage on the output side with the switch off.

The fan motor is not working i did not get manual i want to check fuse first


The fuse diagram should be listed on the inside of the owners manual, and as I remember, the inside lid of the fusebox won't help you. In my experience, the blower motor (fan) goes bad about 30% of the time, the blower motor resistor about 60% of the time, and the climate control module (knob) adout 10% of the time. Look for a bad resistor first, expecialy if it "works", but only has "HI" position. If not, likely a bad blower motor. If the fuse is popped, why did it pop? Yup, you guessed it, fuses don't pop unless there's a reason for it... Motor. the Stick

2000 Volvo V70 climate control problem - blower remains in high, regardless of AUT 0-High setting. Vent selection and temperature controls work. Any idea?


Most common cause of this problem is a bad climate control power stage. The power stage control the speed of the blower fan on different settings, if it goes bad it defaults to full blast. There is a small chance the climate contro lunit itself is bad but more than 90% of the time, it is the power stage. It is located near the blower fan under the dash in the passenger footwell area. It makes it much easier to remove the glove box and knee bolster as well as the cover panel. It is rectangular in shape about 1.5" x 3" and black.

Blower fan won't shut off its or climate control fan keeps running 2003 hyundai santa fe


Probably a stuck fan control relay.
Find the relay and remove it - if this stops the fan. replace the relay with a new one.
