We have had this problem for over a year. It has been to our trusted GMC dealer shop several times with no resolution of the problem. VERY FRUSRATING!! Help, please!

The A/C works perfectly fine. Yet when switching over to the heater nothing but room temp air blows out. This problem started at about 90,000 miles. Im planning on selling the truck soon and i would like to get it fixed. It has been freezing winters with the heater not working. I have had to replace the fan once before due to the wire harness connectors melting to the fan. Could that have started the problem? Or is it the A/C / Heater actuator not working? The truck now has 110,000 miles on her.

My 2006 Sierra 150 truck was fine at midnight, but when I went to drive it in the morning the power steering would not work. The mechanic says the damage was done by a blown "cooler", but I did not have any overheating problems going to my appointment. Only had hard steering problems.

I had a bad CV on the right side and there was a clicking noise. I changed both CVs this fixed the grinding but not the ticking. I found out hubs where making the clicking noise so I just replaced both hubs. After all this in turns there is a roughness still. Also not sure if its related but over rough pavement the whole truck feels loose.

I have put in a new water pump, flushed coolant and put in new antifreeze. There has not been any water in the oil. The cooling system was tested. There was no co2 in the coolant and it keeps pressure. I am lost as to where the antifreeze goes. The surge tanks stays fine for days then will start going down.

replaced water pump, flushed coolant system, new coolant. coolant level will stay up and then drop for no reason. mechanic tested coolant, head gasket. nothing found. now water or coolant in oil.
