This is right out of GM electronic service information.
Blower motor operates at High speed only
• An open between S223 and the blower motor resistor--Refer to Circuit Testing and Wiring Repairs .
• A faulty blower switch--Test the blower switch for an open. Refer to Circuit Testing and Blower Switch Replacement .
• A faulty blower motor resistor--Test the blower motor resistor for an open. Refer to Circuit Testing and Blower Motor Resistor Replacement .
Safe bet....Blower Motor Resistor. The odds of all contacts on the fan control switch going bad at the same time is slim and none. All it takes is 1 circuit path on the resistor to cause your problem.
If your vehicle is under warranty....Take it to the Dealership
If not under warranty...and you want to fix it yourself....here are the steps.
Removal Procedure
Remove the instrument panel compartment. (glove box)
Disconnect the blower motor resistor electrical connector.
Remove the 2 screws (5.5mm socket)and the blower motor resistor from the blower case.
Installation Procedure
Follow the instructions backwards :)
AC Delco replacement part number 15-80202
GM part number 88973260 MSRP $39.58
I found it online $30.53 (includes shipping), i attached a link to the web site.

Most likely it is the resistor that went bad. This is a small piece of electronics that reduces the amount of power to the fan (resists) so that it will spin slower. That is an easy and cheap fix. Don't let the mechanic talk you into replacing the fan motor as well. Sometimes, but rarely, the switch itself goes bad.

Sounds like a short. If the problem was only with the fan, it might be in the switch or the fan speed relay. However since other accessories are affected, it sounds like a wiring problem.

Yes, it s the blower motor resistor switch. Just unplug the resistor and see if the blower fan will run on high speed

its not the fuse or breaker, dont listen to the other guy, its the blower motor resistor or fan control switch.

yes it is the relay for the spped control. sometimes it is in the switch. but it is the relay
