2007 Chevrolet Tahoe Q&A
2007 Chevrolet Tahoe Question: Batt good,alt good, power to fuse box, random non start. No lights- locks- Zip!?
Random times tahoe will be dead. No locks, radio, domes, nothing. No attempt to start. Check from battery to fuse box. All good. Then outta know where she will start as if nothing happened? Radio says 12:00 and engine hours resets. Sick of being stranded. CD player tries to eject at restart ( empty) and only other glitch I've experienced is heater resets from time to time from auto to factory default. Anyone else? Ideas? All wiring is covered in hose so not seeing anything like a bare wire? Yes- batt is brand new voltage correct and contacts clean. - Freebird222Y
My first guess would be a bad ground or positive connection, or wire. If problem happened when you replaced the battery your connections may not be as clean as you think. I had someone use Vaseline on the battery terminals to prevent corrosion, and just that thin film of Vaseline caused the same problem that you have. - Dr Quick
Maybe it's already fixed , but if not , next time it goes dead (no lights , including brakes , & no horn etc.--all things that normally have unswitched power...), maybe turn lights on and start wiggling harness? Have key on , drivers door open so you might hear key chime or see dome light flicker? May help in finding cause of open circuit. Suspect near main or 'master fuse(s)' near or at underhood fusebox. - ziptie12
