Question about 2000 Pontiac Sunfire
OK here is the problem, I can start the car and it runs fine but when i turn on any thing that draws a lot of amps the gauges drop to 0 and i get P1626 and U1040, theft light comes on and check gauges comes on. I have hooked up a meter and took readings at the battery and they stay above 14.00 with lights or a/c and is 14.2 with nothing on. If i turn on the lights and a/c then hit brakes the readings go down below 13.3 and the car has died a few times when the reading keep dropping. I have a new battery , I think it might be an alternator problem or maybe BCM, but I want some other input. Oh i have noticed when gauges drop out if i give it gas they go back to normal. One other thing if I turn blinkers on the lights will dim with them and have noticed the ac/heat blower will drop out if other power acc. are on. Any help would be appreciated ....... 2000 sunfire with 2.2
It is not the BCM, go to any Kragen or Autozone parts store, have them test the alt, the test is free
