I was able to install it on my 2005 Trailblazer In my case, I found that the blower motor would not shut off when the ignition was turned You're off to a great start!
Changing the connector did seem to come into my mind, but my memory may be fuzzy. The process of finding a connector didn't occur to me As part of the new module, the parts needed were provided. For these procedures, I followed instructions on youtube by pfun41 "DIagnose and Replace GM Blower Control Module" and by 1AAuto "How To Install Replace Heater AC Fan Speed Control Resistor Chevy Trailblazer 02-03".
It's a module that has been designed specifically for manual heater Amazon has a few of them. The Manual Climate Control version is only for cars with automatic climate control where the temperature is simply set.
I would assume that it works as long as it has ATC (Automatic Temperature Controls). As well as the wiring, you must replace your wiring harness. If you are mechanically minded, this task should not be difficult. (In my opinion, it's always better to solder the connections than crimp them.)

I was looking for a blower motor control module to replace my OEM. This was the exact item I needed. With an '05 Yukon, I have front and rear climate control with the rear control center console. The only thing I had to do was splice 3 wires (did not include the butt connectors) to convert the harness, which was a perfect alternative to the $200 direct replacement part. This repair took me 20 minutes and is one of the easiest I've ever done.
My 2005 Silverado has been without one of these since I replaced it four years ago on October 16, 2019. After all this time it finally gave up and fried itself on Sunday, October 6, 2019. I could see corrosion on the sensor fins when I removed the plug to troubleshoot, and it was trying to melt the wire harness itself. There may have been a cause behind that, but for as long as it lasted, it worked with no problems. Furthermore, it can be fixed pretty easily. It would be a pain to have to renew my wiring again and use a new one since I'm very particular about it. My next purchase will be a different brand since it is $20 cheaper and made in the same country as Delco. According to me, these components are all the same, so getting the less expensive one doesn't mean it's lower quality than Delco. I just thought I'd mention it. Although I still rate the product five out of five because this is what can be expected from an aftermarket product The product has a relatively short lifespan and it worked well for its short period.
This is an easy I used wire nuts and wrapped them in electrical tape as the original wiring harness instructed. Cut 3 wires and splice in three others with butt joints or wire nuts. It was much easier to remove the glove box after I struggled with the blower fan connector, after cutting the original wiring hardness with enough room to splice back in the original connector just in case GM or ACDelco decides to go back to that again. In my 2003 GMC Envoy with the automatic driver and passenger controls, I clipped the existing wire as hard as I could with the ignition key off and still managed to blow the 40A blower motor fuse when I cut the existing wire. The meter showed 0 even after I verified it with my hands Amount of voltage between the batt and the battery Normally, voltage would be on ground, but in this case it was in the purple control line. This scenario may only apply to models with automatic controls, but you definitely want to replace the 40A fuse, which costs $5 at your local parts store!.
It cost $265 to buy the part and and at a GMC dealer. It appears that the blower motor in my 2007 GMC Envoy SLT with automatic climate control malfunctions (or at least, that was my suspicion). In the glovebox, I accessed the blower module and blower motor and installed a MM on both of them. Twelve were in the controller's hands. There are xx volts in the circuit. 0 volts were present in the blower. As well as the glovebox, the blower module and the blower, I removed them. Suppose I only replaced the blower module, then why would I need to replace the blower? Since it is easier to connect the power cable between the module and the blower if the blower has been The symptoms are There may be a day when the blower works, and the next day it does not. This unit had three speeds even when it wasn't working. When I clamped a dc clamp meter on the purple wire of the blower, I got a voltage of With the old module, the maximum output was 2 amps. I have now successfully installed a new module and am now getting 8 speeds ranging from 1 to 0. Up to and including 14, all of 57a. It is 80b. Thanks to this fix, the problem is now fixed. In the dealership, the part was $265 and the labor was $300. I took one minute to complete it. It takes 5 hours. "
As everyone says, you do have to clip the old cable from the old module (3 wires), two of 18 gauge and one of 22 gauge. Connectors used to attach the boots to the boots were waterproof. I am offering the following advice Make sure the negative battery terminal is disconnected before starting your engine! Tip #2 Check the resistance between the negative terminal of the battery and the chassis ground of the car with your multimeter. If possible, you should have a resistance of less than 1 ohm. It should be no more than 5. I recommend you remove the chassis ground, sandpaper the connection down, and tell me what you need to When your chassis ground is good, your blower motor will be able to function at its highest level.
The resistor module for several GM vehicles has been updated. After installing this kit, I was able to fix my 2005 Chevy Trailblazer which had automatic temperature control code CJ2 for the blower fan remaining on even when the key was off, and also not being able to turn it A black resistor module with a hardwired blower motor wiring connector was used in the old style. New types of wiring require replacing the connector so the sensor, motor, and control wiring are combined in one connector. The resistor module is now separate from the blower connector. This was a great deal on an OEM part, and the aftermarket junk was not worth getting in the way. Don't let any of your GMs leave.
A special auto AC control system was installed in the 2003 Tahoe. Getting the program up and running was easy. In order to give you an idea of the original unit and control panel, I have attached pictures.
Having used the original module which had burnt up, I replaced this one with automatic climate control after the blower stopped working on my 06 Silverado. The factory connector will need to be cut off and a new connector will need to be spliced Two 12 gauge butt splices and one 18 gauge butt splice were used. This is the second and improved design from GM/ACDelco, featuring a beefier heatsink and whatever other upgrades were done internally. The unit took only 10 minutes to install and works perfectly. The fans are all functioning as they should. Most people use wire nuts or solder, but I prefer crimp connectors with heat shrink tubing over the My order arrived on time and in good condition as always due to Amazon's efficient shipping. I paid a lot less for the product than I would have paid at a local parts store, half of what I could have paid elsewhere.
