That code is for a throttle postion sensor. It tells the ECM and TCM when to shift. You should replace it.

Check for cigarette lighter fuse it drive OBD2 power to scanner

Dual climate control on these is not a manual valve adjuster. It is done electronicly with a electric motor on a valve instead of ran by a maual cable. Find this and check the plug for a 12 volt signal. If you are getting a signal replace the valve, if not it could be a blown fuse, cut wire, or a bad climate contol switch.

the map sensor could be the problem for code P0101 hope it helps

Ps101 is not a valid code. Please recheck.

It sounds like a sticking solenoid. If you tap the solenoid with a rubber or wooden mallet (best not to use a hammer but you can) it can free up the solenoid if it is sticking. If this works, you'll need to replace it.

GM has issues with corroded battery cables. Have you removed, cleaned, and inspected each battery cable (from end to end)? Have you bench tested the starter or sent it out to be tested? How old is the battery? Have you had the battery load tested? Please describe (in detail) what you have looked at and tested). The more information that you can give, The faster I can try to help narrow down your search for a solution. The only other things that I can suggest is to look at the starter relay and inspect the neutral safety switch. You may try to start the engine in neutral rather than in park.

the obvious first, check freon... second, check fuses, and finally check that the clutch engages on the ac compressor when turned on (you should here a click and notice a small, momentary difference in the idling of the truck) you can also visually check the clutch by watching the compressor when someone else turns it on. if the clutch is not working, the inner part of the pulley does not spin.

check torque converter

The fuse for this is in the block under the hood. In the lower right hand corner a blue 15 amp fuse marked "info" . (check under the lid of the fuse box)

sounds like the vacum lines thats hooked up to it is disconnected check that first

I don't have the answer, but I am looking for the solution for a 2006 Silverado crew cab.

if it has dual zone climate setting it could be stuck in the cool setting. if it is not blowing any air it could be the duct came loose and it is blowing the air inside the dashboard. it will require you to pull the dash apart to inspect what the exact cause is. it could be anything from a bad temp setting switch in the climate control panel to a bad vac line that that switches the air from hot to cold. any other info you could give me may help such as if it is full electronic climate or manual knobs, dual zone, is it blowing any air or just no hot air.

There's a vacuum problem
