A/C doesn't blow on high

Asked by Mark May 09, 2020 at 04:09 PM about the 2001 GMC Sierra 1500 SLE Extended Cab SB

Question type: Maintenance & Repair

I have a 2001 GMC Sierra 1500, I replaced the A/C blower motor and resistor. Now the fan will not run on level 5. 1-4 blow air but at a very reduced rate. At first I thought I was getting bad a bad resistor but I have exchanged it twice and it's still not blowing correctly. I don't think I got 3 bad resistors.

Answered my own question. I found out there's a high fan fuse under the hood. It was blown, put in a new one and it blows fine now.

    The air is cold but it just wont blow until you are going down the highway 45+ mph. Once you slow down it doesn't blow anymore!
