HVAC fan control

Hi,

A few months ago my 98 Malibu HVAC fan control partially broke. Speeds 1 and 2 stopped working, while 3-5 were still functional.

Today 3-4 also stopped leaving just off and '5'. Kinda annoying.

I'm hoping this is a simple fix/replacement that I can do myself but I'm unsure where to look for the problem.

I appreciate any help. Thank you.

Sounds like the resistor, it is common for the Malibu it is on the passenger side behind the blower motor real close the the fire wall.cost about 25 bucks

my malibu 's air setting are off-like 1, and 2 barely pump out anything while 3,4, 5 work, is the part that u guy talking about have two compintents to it, like the part would be shot is only 1 and 2 opperational ,and the 3-5 adjustings are on a second part?

Yes You just have to replace the resistor. When it goes bad it will take out setting 1 & 2 of the fan, and let 3,4 & 5 run.

Is it in the same place for a '99 Malibu?

Go to http://www.automotiveforums.com/vbulletin/showthread.php?t=199000 for the procedure. The procedure is the same for all 1997 to 2003 models, and is very common.

Note: this is the second place I've posted this reply, but this thread seems more relevant.

I had blower fan speeds 1,2,3 die on my '00 Malibu (second time it has happened, first time was fixed by a dealer 2 years ago). I decided to try and fix it myself this time and went to Autozone and got the replacement resistor pack part for it ($17). After replacing the part, the blower worked on 1,2,4,5 (NOT 3). Looking inside the 5-pin connector on the part, I saw that pins D and C were connected on the new part, but not on the old part. I figured that Autozone had the wrong part, so I returned it and went to my local Chevy dealer's parts department to get what I thought would be the "genuine" part. Sure enough, when the parts guy pulled the AC Delco labeled part out of the box it was the IDENTICAL part (D-C pins connected, colors, size-new one is bigger, both made in Japan, same 4 little lumps on the back, etc., etc...). I'm 99.9% sure that both the dealer and Autozone had the exact same part, but the Chevy dealer swears up and down he has replaced dozens of these and never had a problem with one blower speed not working. Has anyone else here who has tried replacing the resistor pack had this problem? I would rather not give the dealer $100+ bucks to fix what is inherently a bad design.
