This 2006 Chevrolet Pioneer came in with the ill that the blower did non work at any speed. This bushel applies to 2002 -2009 Chevrolet Trailblazers and GMC Envoys,2002-2004 Oldsmobile Bravada, 2004-2007 Buick Rainier, 2002-2008 Isuzu Ascender. The parts are the same but positions Crataegus oxycantha vary for 2004 and 2005 Chevrolet SSR. All with blue-collar A/C controls.

This Innovator has multiple zone, manual of arms a/c controls as seen in the picture below.

Since this is a very common problem I went straight to the blower resistor assembly. It is settled low-level the passenger side of the dash. To approach it the lower hush panel has to personify separate. Two 7 mm headed screws are wont to tie the panel to the bottom of the dash.

Once it is perfect there are whatsoever wiring connectors that have to embody taken loose along with the satellite radio receiver mental faculty. Not all vehicles leave have this module.

With complete of that out of the way of life, I could right away see the resistor and the burnt harness connector affiliated to it.

A little different view. The red electrify is visibly destroyed.

I unlatched the resistance assembly by removing the two 5.5 mm headed screws.

I had to use a screwdriver to prize the connector loose from the resistance assembly.

The trodden connector.

As was common the red and black wires were the main wires sick. The needed parts are available at www.The-Electric-Connection.com . Delight click here to parliamentary law.

Now, it was time to splice one wire at a time. I started with the violent wire and made surely I applied the wake shrink tubing as this wire has power along IT complete of the time. I did non want to brag the fuse Oregon remove information technology either.

Stagger the joints.

Reassemble and this one is done.

Testing is every bit follows. Disconnection the 7 telegram harness connector and inspect. If at that place is some contract of heat damage replace both parts per above instructions. If in that respect is no sign of heat damage then check the following. With the 7 wire harness disconnected check for power on the red wire. Information technology should have 12 volts the least bit times and it gets it's power from the 40 ampere cetacean fuse in the under toughie fuse box. Next with the key on check for 12 volt power to each of the following wires Eastern Samoa you move the electric fan rush along electrical switch from low to high. Yellow / low, tangent / med 1, lt blue / med 2, purple / med 3 and Orange / high. Remember, this test is finished the key connected and the seven wire harness disconnected. Other than the scarlet wire having force at every last times, only one wire at one time will have power on it, during a right test. If on that point is no power to any of these wires during the trial , discipline the fuse in the driver's interior fuse box. If only some of these signals are missing, you will need to audit the cetacean mammal speed switch and related wiring. Besides you should do a drag run on the terminals to check the spring tension.

  • Closing "A" Tan = Speed 2, power through blower switch from HVAC fuse
  • Terminal "B" Yellow = Speed 1, power through blower switch from HVAC fuse
  • Terminal "C" Purple = Speed 4, power through with blower switch from HVAC fuse
  • Terminal "D" Lt Blue = Rush along 3, power through cetacean switch from HVAC fuse
  • Terminal "E" Black = Blower system, ground in the least multiplication
  • Fatal "F" Orange = Speed 5, power through blower switch from HVAC fuse
  • Terminal "G" Red = Rush along 5, Constant quantity king from BLWR mix up under hood

If all of the tests preceding are okay and you desire to go a step encourage, place a test light or voltmeter in the wires going to the blower motor. If the light comes on operating room you have a 12 volt reading, the resistance and wiring are okay and the blower motor is faulty. This can likewise sometimes Be confirmed aside bumping the blower motor with the switches on. If the motor starts after bumping the motor is inaccurate. One behind also murder the blower motor and apply 12 volts (power and ground) directly to the motor. Be blow-by-blow though the motor will tend to jump and roll completely over the place. Hold it firmly and be sure you are clear of the impeller every bit it could hurt you bad easily.

Unmatched other note. If you give birth an amperage caliber, prove the electric fan amperage attractor while it is mounted in the cetacean case. Arouse soar amperage could burn up to about 28 amps. Amperage draw at high electric fan should be in the 18 to 24 amp range. The lower the meliorate. Controlled cabin zephyr filters (if present) and dirty evaporator cores will cause a blower causative to pull off much current spell reduction air flow volume. These cardinal conditions combined will significantly keep down the life of any blower resistor.
