Question about GMC Cars & Trucks
Hi Jeff. You shouldn't have to disconnect batteries for four months of storage, but it's probably a good idea to do it anyway...just to be safe.

I have the same problem and have trouble codes 35 and 36. I found out that there is a computer module that needs replaced as it sits low in a valley and gets hot and seperates. I am reseaching about the a/m fix that installs the new module away from heat.

SOURCE: location of blower resistor for 2005 GMC sierra
Hi, the blower module that is located at the bottom of the heater box, next to the blower motor, above the panel below the glove box, has a tendancy to go bad, possibly overheat, and melt the larger of the two connectors. This can lead to one or all sppeds inop. the module will need to be replaced, and th connector inspected. If the connector is melted, or discolored, it needs to be replaced. A pigtail with wires, and connectors, as well as the resistor, should be available at a local GMC or Chevy dealer. Good luck...Coop
