Having problems with your 2005 Chevrolet Silverado ?
I have a 2005 silverado my heater switch works on every number except 3 do you think it is the switch or relay
Most likely the heater control panel bad. the whole assembly on the dash where you turn the heater switch to a higher level. you can replace with new or if you choose to,used part. if you are mechanically inclined, it's not that hard. alot of screws to remove the panel. if you need a diagram,please repost and ask for a diagram and an expert will be happy to assist! thank you for choosing fixya.com
This is most likely your blower motor resistor. When these fail, one or more of the fan speeds will not work. It will be located under the the dashboard on the passenger side. It is right next to the blower motor, and costs around $45 new. I hope this helps.
