Is the blower resistor stealership only

Thanks !

mine was 19 bucks at advance

Mine crapped out, so it needed replacing.
I have the RPO code CJ3 (see pic below) and according to this post I needed the double hole resistor. I removed the bad unit and in fact I had the single hole resistor. So going by the RPO code isn't fool proof. Best bet is to remove the cover and look.
I'm not posting this to say anyone is wrong, just giving a heads up.

List price from Car Quest $40.49

However, I have the 40/20/40 manual dual zone a/c and the pn listed above (89019089) is incorrect for my truck. The resistor itself works but the mounting tabs are different.

I did some more snooping on google and came across this little nugget of info. This info is based of your RPO build codes so it makes it nice and easy.

To locate your RPO code, look for the sticker in the first picture attached.

You can find this in the glove box. Locate the code pictured above.

If it has a "CJ3" or a "C42" but NOT "DO7" then the correct blower resistor is the 2 hole resistor
AC Delco PN 15-81086
GM PN 89019088

The resistor will look like this

Notice the two holes per mounting tab. This will be the main difference between this and the next one.

If your RPO does not have have the above listed "CJ3" or "C42" then the 1 hole resistor is the correct one.
AC Delco PN 15-81087
GM PN 89019089
It will look like this, notice the 1 hole per mounting tab.


If you have the auto AC climate control, then yours looks completely different. Your RPO code will be "CJ2" Not sure on the part numbers as AC Delco doesn't have a part listed for the auto ac.
AC Delco PN
GM PN

It will look like this


There is a really good kit out by these guys http://www.motorcity1.com/Truck_Kits.htm, comes with a new connector, resistor and connectors. Wish I found this site before I ordered the wrong parts. Hopes this helps people searching in the future. Be sure to pop your head under the dash if you haven't already to make a visual check to see if you have the 1 or two hole version of the resistor.

BK tool which cover did you remove too expose the resister? i want to replace mine also. wanted to last year but did not spend the time on it.

Under the glove box is the cover that goes over the blower motor and resistor.
It's held on by 3 screws. I removed the 2 easy ones (right side and middle), but the third one on the left was a tight squeeze to get to, so I just loosened it, then swung the cover down and out.
Then you will see the resistor on the right in front of the blower motor.
