Ali, there is a recall for the drivers side door master switch. I believe 04' was included in the recall, regardless this problem affects ALL years of our platform. Water is able to penetrate the switch, say you open your door when it's raining out. Eventually the switch will start to melt out and can be a fire concern. 2 ways you can do this, call the dealer give them your vin # to see if 04 is included in the recall. OR pull one out of a wrecking yard, BUT, have the dealer on the phone when you do to give them the serial # off the master switch. Some of the newer TB's already had the problem fixed.

On the I6 engine, it's right below the alternator.

Shane, the TPS is located on the throttle body and cannot be removed from it. Must buy the whole throttle body which includes the TPS.

expanding and overheating transmission oil can be from 1 excessive oil in the transmission 2 slipping bands/clutches 3 excessive overload or speed 4 low transmission oil pump pressure

Has to do with the timing in the monitoring period, Bosch isn't quite within the specs for our vehicle. Hopefully you used a different brand 02 sensor? Other problems could be low fuel pressure, faulty injectors or an intake leak. Check your intake bolts, our intake is plastic and the bolts DO come loose often. Re-tighten, erase the code and see if that works.

Just sayin, could be a bad antenna connection, or buy another one on ebay, WAY cheaper than a shop.

For our I6 engine....The MAP sensor is located on drivers side right next to the firewall very top, easy to get to. It does have a seal, as you'll notice when you pull it out, very hard to leak air though. It CAN be clean with a MAP sensor spray cleaner, usually doesn't work though if the sensor is going bad. Using the compressor to clean your air filter only works so many times. I'd replace that. On a side note, our engines love AC Delco 41-103 spark plugs, others won't run quite as well.

Low power lean conditions cracked air intake tube GM Testing by a qualified repair person with proper diagnostic tools is the way to a proper fix , not someone guessing !

Dexron Vl Walmart has it under its "SUPER TECH" line of products. $4.27 per quart.

with an engine upside down and running, the oil pump runs dry the bearings are running with out oil or lubrication with the engine shut off the oil will settle in the pistons and will leak past the rings int the combustion chambers, into the rocker covers and into the air inlets and manifold the coolant will be contained as the system is pressurized and cannot get anywhere it is not supposed to get to transmission /diff oil may have leaked out of the breather holes but otherwise will be contained should you purchase the vehicle , it will be necessary to remove the sump and check the bearings for damage, replace the oil pump. Remove the plugs and turn the engine by hand over to push any oil out of the combustion chambers with the vehicle sitting right way up any oil will run back to the sump except that which is in the air intake and manifold Basically it should be in a recoverable state,if the engine was shut down quickly enough check the crankcase around the engine mounts for cracks as the engine weighs a lot and the throwing around can stress where the mounts are
