cluster lights flashing
It went out completely, I replaced the fuse and they're fine now. Perhaps the fuse was burned but still had a small enough gap to arc???? Not sure but it's fine now- skynyrdcat

cluster lights flashing
07 COBALT 2.2 My cluster illumination light comes on, goes off, on off, on off at a steady rythm. Doesn't matter if the head light are on or not, as long as the key is on it will do this. Any thoughts? Thanks- skynyrdcat

P0976 question
Yes and no. Actually, I was reading the diagram wrong (the all data tcm diagram is backwards to how it actually lines up in the vehicle). Fortunately the plug has the 1 and 37 wires labeled so I was able to work backward from there. I originally thought the TCM sent power to the solenoids and...- skynyrdcat

P0976 question
Battery voltage 12.0. IGN to TCM 11.8 TCM to 1-2 solenoid = .2v TCM to 2-3 solenoid = .3v I'm thinkin the TCM is shot. It should have ignition voltage to both solenoids with the key on, and then ground one of them accordingly. If I have power to the TCM and none coming out, I think that...- skynyrdcat

P0976 question
Some of the all data stuff doesn't line up... Some diagrams show the circut with a 15a fuse, some show it with 10, etc and one diagram will show RD/WH wire color and the next show a different color. I'll check the battery voltage when I get home. I think I checked it but didn't pay much...- skynyrdcat

P0976 question
If I'm getting less than 12 to the fuse could that be the problem? The TCM is supposed to give ignition voltage to the 1-2 and 2-3 solenoids, and control them by providing a ground path for either. Ignition voltage would be 12.5v right? I found where the harness was rubbing the corner of the...- skynyrdcat

P0976 question
Digital yes. I removed the trans fuse, put the blk dmm lead on the neg battery post and put the red on either fuse terminal. I have voltage on both terminals less than 12 on the IN side and over one on the OUT or trans side- skynyrdcat

P0976 question
i HAVE THE DREADED 976 on an 07 cobalt 2.2. When I check the trans fuse in the engine compartment I have 11.3v on one side ans 1.7v on the other side. I assume that it's a short since it's hot on both sides, just wanted to get some other opinions on it. Thanks in advance.- skynyrdcat
