My 2007 Chevrolet Silverado Classic is having some electrical system trouble. Since it's been so cold and disagreeable lately, I took the easy if expensive way out and let the dealership diagnose it. (The automotive electrical shop I send starters and generators off to for rebuilding wouldn't touch the truck.)

The dealership says that the ignition switch is bad. I'm not so sure I believe them, as it appears to do little more than send wake-up signals to the various computers. That is, if the wiring diagram can be believed. The whole sequence of events is a long story (some video does exist and might be published in time) starting with the engine hours counter suddenly resetting itself and the blower fan not working on any speed other than high. It got worse from there, with the truck having fits about its ABS and brake system, and dropping out of cruise control if the fan switch was operated. Later I discovered that operating the transfer case would induce the same misbehavior. Ultimately, the blower motor stopped working completely as it had blown a protective fuse on the resistor pack.

2003-2006 and the "classic" 2007 truck models are infamous for having parts of the blower motor wiring burn up, and the dealership found that had happened with this truck. (It must have happened relatively recently, as I never noticed this when replacing the resistor pack and blower motor, both of which were bad. The blower motor would somehow still run, but measured 0 ohms resistance.) The dealership was going to charge for this repair, to the tune of some $500! If you have a similar truck with manual climate controls that is less than 10 years old or has fewer than 150,000 miles on it, DO NOT let a dealership charge for the repair. GM has issued a service bulletin under which burned up wiring, blowers that do not function on all speeds and/or are stuck on high will be repaired AT NO COST and regardless of ownership. I will post a link to this text later on. If you live in Canada, it appears that a recall was done there.

So...back to the Buick Century I drove. Apart from the fact that the HVAC blower and resistor pack are crammed into near inaccessibility and the 3100 V6 engine's possible intake manifold gasket issues, I thought it was a fine (if unexciting) little car to drove. It certainly seemed to have a comfortable interior and seating surfaces.

Yes, I meant to say "roller skate with an engine" instead of "roller skate with wheels". Most roller skates have wheels. ;-)
