2000 Chevy Mallibu Sign up here! Search this forum this category all forums for All words Any words Whole Phrase (search options) Auto Repair Home>> Automotive Repair>> Automotive Wiring and Electrical Yourdogsdead New User Aug 2, 2010, 11:36 AM Post #1 of 4 (1127 views) 2000 Chevy Mallibu Sign In My problem is that the fuel and engine temp gauge work intermittently. They are off for the first 10-15 minutes and then they kick in. Same thing for the A/C and Heater blower fan. They refuse to work no matter what. I replaced the Ignition thinking that was the issue, and now the gauges and blower refuse to work at all, no matter how much time has passed by. My other two problems could be the BCM or a loose grounding somewhere but I am unsure. Any help is appreciated.

You can add ground to what should be ground with jumper wire and clips to see if things snap to. Not wires - just grounding metal from known ground metal of body. There may be fuses or a fusible link underhood that has given out as well. Look for one blown fuse or a wire all wrinkled up, T Yourdogsdead New User Aug 3, 2010, 4:57 PM Post #3 of 4 (1095 views) Re: 2000 Chevy Mallibu Sign In I opened up the fuse box and noted some corrosion on the relay to the HVAC Blower or something along those lines. I replaced it and it still ceased to function, but I have not noted anymore corrosion on the new relay. Can you be a little bit more specific on the details on how to test the fuses? Do I need any special equipment? Tom Greenleaf Ultimate Carjunky / Moderator Aug 3, 2010, 6:09 PM Post #4 of 4 (1087 views) Re: 2000 Chevy Mallibu Sign In Fuse testing. Test light would light on one side and not the the other - bad fuse even if they look good by eye............
