Location Of Hvac Blower Relay

[knightgang]

I have a 2001 1500HD, Crew Cab 4X4, 6.0ltr with Computerized Climate Control. The AC Blower just stopped working one day with no indication that anything was wrong. The blower motor works fine when 12vdc is applied to it, but when plugged installed will not work. I think it is just not getting power. I thought it was the blower control module (my model has this instead of the blower motor resistor). However, after replacing the control module, it still will not work. All fuses and relays (that I can find) seem to be good. The Chiltons manual says that there is a blower relay (on the 99 to 02 models) attached to the blower motor housing under the dash. This must be where my issue resides, but I cannot find this relay. Can someone tell me where this is located so that I can fix my air?

 

Thanks,

Eric

It is next to the blower motor. Look for a plug with wires coming out of it.
