05 Yukon blower keeps running

[rthacker]

2005 Yukon SLT, a/c fan keeps running after engine is off, key removed and door opened. The only way I could get it to stop was by removing fuse under the hood. Also the fan speed does not adjust at the controller.

Check your blower motor resistor unit. Should be under the glove box area. Apparently, the relay goes bad in side the module. Something like these here at RockAuto, could be your solution.

Just replaced the blower motor resistor and harness in my dads sierra and it fixed all of those issues. While i was down there I replaced the blend door actuator as well. The air is blowing better out of the vents. Here is the link to the resistor motor/harness I ordered https://www.amazon.com/gp/product/B078J3B4S8/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
