Hello,

Unforunately, late last night I connected the battery in my 94 grand cherokee backwards. I was luckly and the car still starts and drives OK. One problem- the power to the stereo, heat and a/c cuts off when any door is opened. The interior lights work but they flicker on and off as does the power to the vehicle information center. The check engine light has also been on since this misadventure. I have been told the the ECU should be OK since the car starts and drives.

thanks for your help,

James

You may want to have that checked out by a mechanic. You could of shorted our some electrical componets in your car..and messed up something in your alt.

I'd bet your Jeep is in "limp home mode" a redundant and limited ignition program. You might have fried the comp. don't count it out yet. On the bright side you may just need a new battery. Thats a scary thing crossing a battery I did it once-in a beetle, no electronics- won't do that again! Good Luck!
