I bought a 1997 Grand Prix SE, I noticed that the speed nob was broken off a/c, and thought nothing of it, then I noticed trip computer lights were off. My wife looked down on floor of passennger side and said whats this, and pulled a wire hooked up to a toggle switch from under mat,Hmmm, I turned on toggle and a/c fan came on and so did the trip computer lights, the only thing is that the blower is stuck on high(5), with knob broken off, I stuck needle nose pliers in and turned the blower speed switch to the left towards off possition, and the only thing that happened was the trip computer lights went off. I shut car off and started it back up with toggle still in on possition, blower still on high, turned speed knob back to 5 and trip computer lights came back on, but there was a clicking noise on left side of dash and head lights were flashing on and off. turned toggle off, turned car off, restarted car and clicking and flashing head light were gone. anyone had this prob, So I can fix it and trace line to toggle back to its soarce and hook it back up.
the power to toggle is comming from fuse box to toggle and red/black wire going to a/c somewhere.
I bought car off mexican lady who says "I dunno" when I ask her about it.
