Blower fan resistor location

the car has 26 relays!@
and 1 to or 3 fans
are you saying the heater/ A.C blower is dead./ the HVAC?
or engine fan (its mech for rad)
or condenser fan, no symptoms posted, just relay hunts.


my guess is you dont know how the blower in the heater works.
so will cover that.
The HVAC.
First test is blower in high, failing is bad fuse.?
if lower speeds fail, (a top clue) then the blower resistor is bad.
but only on the manual hvac option!

lets backup,I have full parts list on your car, here, USA. spec
the car came new with 2 class type of HVAC
manual AC with blower resistor
or
full auto system that as a new brain box, and a transistor box
that controls blower, at all times, its just a transistor. (no brains)
some cars with the full auto HVAC feature
have a self test mode.
and self calibration feature (learn) all this is in the BIG BOOK.
apples and oranges, different to the extreme.
so instead of me guessing car you bought. ill tell you to RTM

just 4 bucks, and only covers that exact year, and car only.
not a clone book as the folks post here , RAG books.
the real deal here from suzuki actual....

the BIG BOOK. see chapter HVAC and read.

you possibly have a bad blower motor resistor. It is located behind the glove box. First check to see that there is power to the blower motor on the black wire at the blower motor. If there is power than ground the dark green wire at the blower motor. if the blower motor runs at full speed than the resistor is usually the problem.

you can also check for continuity between the dark green wire and the dark blue with grey wire at the resistor. Note where those two wires are in the connectors. remove the connectors from the resistor. check for continuity on the pins in the resistor where those two wires where attached. If there is no continuity than the thermo fuse has blown in the resistor and the resistor will need to be replaced.

More than likely it's your blower motor resistor, but first thing is first check for blown fuses. If fuses are all intact locate the resistor which is usually located under the dash on the passenger side close to the blower motor case.( which will be a black plastic cylindrical box) The resistor will have a wiring harness running to it. With the key in the on position and the fan turned full on slowly move the harness around if the fan starts working, you have a bad connection or broken resistor. Which is common since people accidentally catch the wires with their feet or stretching on a long trip. If you replace the resistor disconnect your battery first, resistor is usually held in with a couple of screws, remove and be careful when installing new resistor they can be a bit fragile, best of luck!

Please check for a blower resistor problem. The fan speed is controlled by a resistor which controls blower speeds. The resistor works the lower speeds while usually high speed bypasses the resistor for full fan speed only. You either have a resistor or resistor electronic module. Google location for locaton of resistor. ( mini one blower resistor location) There is alot of info that may help you.

More than likely it's the blower motor resistor. Gm's wonderful electrical engineers decided it was a good idea to run constant power to the high speed fan relay which is part of the resistor assembly. When the relay stick the fan stays on. The resistor is located under the dash on the passenger side ne'er the blower motor. There is a plastic trim pannel that will need to be removed from under the dash in order to see it. It is typically help in place with two screws that you will need a 5.5mm socket to remove (yes it's a 5.5mm socket). Lmk

Hi,

If you're referring to the heater "FAN" running continuously, then its likely to be your blower motor resistor.

The heater blower motor (under the dash) has constant power supplied from the battery, but is controlled by the blower "resistor" - usually mounted on the blower motor assembly. If one or more of the blower resistor coil wires are faulty, the motor will either not work on one of the fan settings, or will constantly run by itself.

I believe You have a bad blower motor resistor.You can find this resistor close to the blower motor.There will be a 2 wire connector that goes from the resistor to the blower motor.Good luck.

The blower resistor should look like a credit card if it is manual air and it is located near the blower motor. Remove connector and then two screws and it should slide out. Replace with the new one. If you have auto air then the blower motor is regulated by a fan control amp which is located behind the glove box.

by the blower moter always being on i would think it would be the blower motor resistor, this controls fan speed and is located under the dash in the blower case easy to replace.

Replace heater blower resistor.located on the passenger side fire wall.I had same problem.New ,$200. wholesale (dealer only)I bought mine off an auto savage for $20. !!!Fan now works fine !!good luch !!
