’00 Olds Alero fan problem

I realize that this is not audio install, but you guys know a little about everything. My brother-in-laws 00 Alero only has high speed on the AC blower, low and med are dead. Before he buys a new switch, something tells me that it may be a relay somewhere??? A friend had a Dakota with the same symptoms and it was a relay. Any guidence??? Update: I'm told that there is a resistor block somewhere inder the radio or under the glovebox that is a common problem.

Here is a diagrahm of the location for resistor block assembly. Hope this helps.

Hey Furflier...there is no link, please try again..Thanks!

Ok, letstry this again. I am going to have to put this in 2 post , because of the size.

You need to put the file extension in or the pic won't show up, https://www.the12volt.com/installbay/uploads/249_1.jpg Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

Where do I put the file extension at. I didn't see a place to put it. I thought all I had to do was tell it to uplaod the image.  I am not all that great with computers. Is there a step by step instruction somewheres on this site.

HotRod item #8 is your resistor block. It is located just above the blower.
