I cannot reset my trip Odometer. The miles are showing, this part is working, but it will not go back to 000 when I push the reset button.

SOURCE: 2002 Buick Rendezous odometer reads "error"

sound like odometer worn out or wiring problems.

this system has self testing capabilities, have any GM dealer test it for codes and proper function, If I had to guess I would say the climate control head is defective.

check the fuse and relays, check the fan too

Check to make sure that you have enought freon to engage the compressor, then you will need a flow chart to take you through the rest of the steps necessary to diagnos this problem. The Electrical system manual for Buick is the only one that will have the proper information for you to walk through the steps to dead head it. There is a HVAC programer that is behind the floor heater duck work. It has a numbering system that goes from (2) rows of pins that go 1-16 for terminals.On terminal 5-7 with ignition in run position, you need bat. votage. Terminal 10 & 11 you need 4-5 volts. Neither 10 or 11 should be unplugged just yet since 10 feeds 11 pin. If there isn't any voltage at these pins, check for corrosion on the pins theirself, or for the pin that it may have slipped back out of the connector. Good luck.

The climate control cpu could be going bad. My Riviera had a fried plug that went to the climate cpu and I replaced just that. To check it out it can be found behind the glovebox.
