Car Forum / Chevrolet / Chevrolet Malibu / August 2005AC Switch not working in position 1, 2, and 3 but works fine in 4 and 5. Whats the problem here?
Got a weird AC fan switch problem that just popped up on my 2003 Malibu LS. When I switch on the fan to position 1, 2, and 3 it does nothing although the AC light comes on as if the AC is operating. Once I turn to position 4 and 5 it blows cold air on 4 and blows more on 5. I checked the fuses but all are OK. To me it's odd that the switch will not work at position 1, 2, 3 but works fine at 4 and 5. What do I need to look for to solve this glitch? TIA for any help and info you might direct my way. Tha RagMan If your vehicle is like most others the most likely cause of your problem is a failure of the blower speed control resistor module. Very typical failure. > Got a weird AC fan switch problem that just popped up on my 2003 > Malibu LS.

After posting the question I did a google groups search and came up with the blower resistor module answer that you good folks shared. One question that wasn't answered is where is this resistor module located? What does it look like to identify and how hard is it to replace? Does anyone have a part # for it for a 2003 Malibu LS? Can it be purchased aftermarket or does it have to come from a dealer? Mucho thanks to those of you who stepped up with the answer to this one. Tha RagMan New resistor assembly is about $20 at Advance. Procedure below: Document ID# 675187 2003 Chevrolet Malibu -------------------------------------------------------------------------------- Blower Motor Resistor Assembly Replacement Removal Procedure Remove the right side instrument panel (IP) insulator. Refer to Closeout/Insulator Panel Replacement - Right in Instrument Panel, Gages, and Console. Disconnect the blower motor resistor assembly electrical connector from resistor assembly. Remove the blower resistor assembly screws. Remove the blower motor resistor assembly. Installation Procedure Install the blower motor resistor assembly. Notice Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems. Install the blower motor resistor assembly screws. Tighten Tighten the screws to 1 N·m (9 lb in). Connect the blower motor resistor assembly electrical connector. Install the right side instrument panel (IP) insulator. Refer to Closeout/Insulator Panel Replacement - Right in Instrument Panel, Gages, and Console. >>it sounds like the resistor i just had to replace the one in my 2002 >>Malibu did the same as yours [quoted text clipped - 15 lines] > one. > Tha RagMan >New resistor assembly is about $20 at Advance. Excellent info. The resistor sure sounds like the fix to the problem. Will pick one up and get it installed then report back to the group. My sincere thanks to all who contributed helpful info to this problem. You did good ! ! !

There is just enought room to get a small open end wrench in, you probably won’t be able to get a socket wrench in there. Group; I just successfully completed the blower motor resistor replacement and I want to tell each of you who contributed information concerning same that I absolutely would have never been able to accomplish it without your informational help. Even then it was a chore but one that I'm sure saved me at least 1-2 hours labor at a dealer shop. If anyone has a shop rate book I would be curious as to what is listed for this replacement. Once again my sincere thanks to each of you for helping me through this to the tune of about $23 vs a probably cost of between $100-$200 had I had a pro wrench do the task. I learned something and I saved a few bucks in the process thanks to you good folks. A round for all my friends here in the group! Tha RagMan Dealer part $32.00 labor for installation .5 so your looking at about $72.00 +taxes installed here in deep south texas..Wait time is 20 mins...

Steve Cook; Thanks for the info. The part is a little higher then I paid but the installation time quote is much less then I expected. I'm sure a pro wrench could do the job much faster then I but that .5 number in my estimation would be pushing the limits as getting at the resistor was a pretty intense challenge. Especially if you're not a career contortionis. That's again for the info. Very interesting.

Very interesting. > Tha RagMan There is an easy solution to the contortionist problem - Alldata suggests the you take utility knife an cut the rear trim in a rectangle shape but only three sides and push it towards the fire wall - then you will have the space to unscrew the rear screw . after you are finished - glue it back into place. Sorry I did not suggest this earlier!! >There is an easy solution to the contortionist problem - Alldata >suggests the you take utility knife an cut the rear trim in a rectangle >shape but only three sides and push it towards the fire wall - then you >will have the space to unscrew the rear screw . after you are finished >- glue it back into place. Klinger; Thanks for the follow-up to the instructions. Your suggestion would have made life a little easier but I got through it and the dirty deed is done. The main problem I had was getting the plastic part back on right. The plastic part would go on easy enough but getting the internal round pipe to engage the flexible hose was the tough part. I believe I got it right as everything seems to have air blowing from where it is suppose to. I am really happy to have done this job myself and give a lot of credit to you all that provided the info and guidance to get it done. I much appreciate your help and support. Thanks! Tha RagMan All you need is a 1/4 5.5mm swivel and a small extension...R-N-R time 5 mins..You dont need to put the rear screw back in it sits and seals just fine with the one...
