Gotta tell you, this question had me a little confused. Below are 2 wiring diagrams for you. One is for the cruise control circuit and the other is for the air conditioning circuit. The reason I gave you those is because it seems according to the wiring diagram in the cruise control that the fuse for the cruise control goes to the HVAC (air conditioning). According to the wiring diagram for the A/C yes that fuse also controls the ignition power for the A/C controller. In any case the fuse that would cover the cruise control is the number 30 fuse in the fuse panel located under the hood of the vehicle. Below is a picture of the location of the fuse panel and also fuse layout diagrams for the 6 cylinder and 8 cylinder engine vehicles as they have different layouts depending on the engine size. I hope this helps you and good luck.

Hi Eabyrd05.
It's possible that you have a Starter or Flywheel/Flex-plate issue. Your starter Bendix may not be completely disengaging from the flywheel like it should. I would take it to a mechanic that you trust and have them pull the starter and look at both the Flywheel/Flex-plate, Starter Bendix and solenoid. Hope this helps.

Check that the wire connectors are clean and completely plugged together. No electric, no run, no sound.

Check your linkeage bushing (plastic). Dorman makes a replacement, these tend to break. In the mean time, you can Jerry rig it. I've seen people use zip ties to get by.

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.
