Blower motor fuse location - 1991 Pontiac Trans Sport

The fuse panel on a Bobcat 863 skid steer loader is typically located in one of several places. It could be located in the cab of the machine, near the floor on the left or right side. It could also be located in the engine compartment, either on the side or on the firewall.
To check the fuse for the blower motor and windshield wipers, you will need to locate the fuse panel and then locate the specific fuse for these systems. The fuse panel should have a diagram that shows the location of each fuse and its corresponding circuit. If the fuse is blown, you can replace it with a new one of the same amperage rating.
If you are unable to locate the fuse panel or the specific fuse for the blower motor and windshield wipers, you may want to consult the operator's manual for your Bobcat 863. This should provide you with more detailed information on the location of the fuse panel and the specific fuses for these systems. Alternatively, you can also try contacting a Bobcat dealer or a qualified repair technician for assistance.

Fuse for rear air ????? No air coming from rear vent's ? That would be caused by the HVAC blower motor not working . Probably not a fuse issue , if the fuse is blown you have a bigger issue . Fuse's don't just blow for no reason - electrical short circuit, too much current draw etc.. . More then likely it's a problem with the blower motor control module or the blower motor . Located behind the right rear trim panel . But go ahead an check the fuse anyway , fuse # 26 - 25 amp located in the underhood fuse / relay box . marked RR -BLWR/ 110 VAC
Auxiliary Air Speed
The auxiliary blower motor is controlled by the front auxiliary blower motor switch. If the vehicle is equipped with rear DVD (U32), the auxiliary blower motor can be controlled by the overhead console, vehicle entertainment system (VES). The front auxiliary blower switch must be in the AUX position in order to control blower speed from the VES. The VES will send a class 2 message to the HVAC control module requesting a blower motor speed.
The auxiliary blower motor control module is an interface between the HVAC control module and the auxiliary blower motor. The auxiliary blower motor speed control, auxiliary blower motor speed signal, blower motor speed control, and ground circuits enable the control processor to operate. The HVAC control module sends the commanded blower motor speed to the control processor through a 0 to 8-volt linear ramped blower motor speed control circuit. As the blower motor speed control voltage increases, the blower motor speed increases. The control processor sends the actual blower speed to the HVAC control module through a 0 to 12-volt blower motor speed signal circuit. The control processor uses the blower motor ground as a low side control to adjust the blower motor speed. The underhood fuse block supplies 12 volts to the blower motor through the blower motor voltage supply circuit.

Doesn't work on any speed ? high - low . Does your's have manual or automatic climate control ?
Don't think a fuse problem , blower motor control processor more then likely .
Blower Motor Control Processor
The blower motor control processor is an interface between the HVAC control module and the blower motor. The blower motor speed control, battery positive voltage, and ground circuits enable the control processor to operate. The HVAC control module provides a pulse width modulation (PWM) signal to the control processor in order to command the blower motor speed. The processor supplies 12 volts to the blower motor through the blower motor voltage supply circuit. The control processor uses the blower motor ground as a low side control to adjust the blower motor speed.
Look here for fuse location an wiring diagram's http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size. Under system click on HVAC , subsystem HVAC controls . click the search button then click on the 5th blue link . This show's fuse location an wiring diagram for the blower electrical circuit . If you don't know where the rear fuse box is ,it's under the rear seat . It would be easier to just check under the passanger side dash at the blower motor control processor at the orange wire .
Do you know how to test electrical circuits with a voltmeter ?

GMC Yukon HVAC Blower Motor Won Turn On

(1) possible blown fuse.
Note that fuses blow for a reason - seek out the reason, or it will blow its new fuse too.

The main fuse block is located inside the left side of the engine compartment near the battery. There is also an interior fuse panel located just above the left side kick panel.

Interior Fuse Panel
The interior fuses simply unplug from the fuse panel. Use the fuse puller tool provided with your car to remove fuses from the panel. The tool is located on the back of the interior fuse panel cover.


(2) possible blower motor dead. See maintenance manual excerpt below.

(3) possible blower motor relay faulty. Location of Blower relay:
Under hood, drivers side, front engine area,rear of headlight housing; relay mounted on drivers side of radiator shroud.


1990-92 Mazda 626 and MX-6
See Figure below

1. Disconnect the negative battery cable.
2. Remove the glove box and the underdash cover.
3. Detach the electrical connectors from the blower unit.
4. Remove the blower unit-to-fire wall attaching bolts and remove the blower unit assembly.
5. Remove the blower motor fan-to-motor fastener.
6. Remove the blower motor-to-unit attaching bolts, then remove the motor.
7. Installation is the reverse of the removal procedure.

Check fuse #14(10amp) located in fuse box under driver steering wheel behind the lower dash cover.
Check fuse#12(40amp) located in fuse box under hood.
Replace fuse(s) if any are blow.

If fuse are good.Check blower and transisto next.
Do steps 1-3 with turn key on
1. Unplug connector and check for 12v at the blue/white wire at the blower motor(2-NAT)
-if there's no voltage you might have a bad relay or open in the wire
-if there's about 12v, go to step 2
2.Plug connector for blower motor and unplug connector for blower transistor(4-NAT). Take a jumper wire and jump the blue/black wire to body ground.
-if blower does not run, replace blower motor
-if blower motor runs, go to step 3
3.check the black wire at(4-NAT) for good ground.
-if you have good ground, then replace blower motor transistor.
good luck

C-19 Blower motor fuse 25A located in cabin fuse box. Left hand footwell on LHD vehicles, right hand dashboard on RHD vehicles.
Start by checking blower relay B-36 in the engine compartment fuse and relay box. Remove the relay. Jumper directly from battery to pins 85 and 86. (also see here: http://www.fixya.com/cars/r5544622-wire_relay if you dont know about relays) The relay should click Now measure across pins 30 and 87. Measurement should be 0 ohm.
Remove the blower motor(3 screws on the bottom of the unit under the passenger side dash) and connect jumper leads from the battery directly to the blower motor to see that it operates.
The blower motor resister is mounted on the ducting between the motor housing and the heating unit. Remove to test
Measure :

• pin 1-2 : 2.4 ohm
• pin 2-4 : 0.9 ohm
• pin 2-6 : 0.28 ohm
• pin 2-3 : 0 ohm

I have the same Question .....WHERE is the front blower relay located? Not the resistor or the speed controller.....but the front blower relay!

There is a blower motor resistor located up under the passenger side dash. I believe there is actually 3 fuses that can cause problems with the blower....relays/fuses should be located in the engine compartment fuse block. They are High Blower fuse-HVAC fuse-Radio/HVAC/RFA/Cluster/etc...fuse. Hope this helps.

Fuse blower motor is not in the fuse box. It is located outside. lOpen the hood, on the driver side near the fender, about 1 feet from the fuse box toward the direction of the radiator, there is a retangular about 1x2 in with wire coming out from each end. Snap it open, inside is the the wire fuse.
