Problems with 2005 GMC Canyon EQUIPMENT

Air conditioning fan abruptly stopped working on all fan speeds except "4", the highest position. checked internet for possible solutions and found that there have been numerous failures exactly like mine. all involved the "blower motor resistor assembly, connector and/or wiring harness" shorting out. scortching the connectors, resistor assembly and causing the plastic to melt/burn. gm parts at local dealership had replacement parts and i was able to resolve the problem. speaking a gm service advisor, he confirmed that there are numerous repair problems with these parts on the gmc canyon/ chevrolet colorado 2004-2007. but no explanation for why they are failing. numerous internet reports with photo's showing damage and explaining problem most requiring multiple or repeated repairs. old parts are available. *tr

Brand new truck, have owned almost 1 year. had to take truck in for slow acceleration problem as well as hard to crank. could not pull out into traffic, had to wait until there was no one on the road because i would try to accelerate then it would stop/pause for a second then start to go again. took my truck to the dealership which they found one of the heads in the engine needed to be replaced. (which at first they told me i had a slow misfire on piston #2 and they had to replace a spring and a coil) a month later i finally got my truck back. one week later i heard a knocking noise so i took my truck back to dealership and was told my oil was low so they topped it off (didn't work by the way). still having hard time cranking periodically throughout the day. took it back to the dealership, they kept my truck for 4 days and said they could not find anything wrong with it except a loose starter bolt that they tightened. truck still cranking funny but was told there was nothing further they could do for me. *jb
