1993 trooper RS 2door, everything worked fine 2 days ago, My low fuel light comes on so I stop for gas, 5 minutes later I start the engine and now I have o2 light on, brake light on, battery light on, low fuel stays on, the heater fan stopped working, the cruise light stays on but the cruise stopped working. I lose voltage as I drive. I have tried a different battery same problem.Need help as to what might be causing all these problems, otherwise it still runs ok, thanks

 

Are you losing charge? Just a thought, that it sounds like alternator.

 

yes Im losing charge but that happened at the same time all the warning lights came on. I dont think a bad alternator would cause all the other problems, the warning lights, the heater fan, the cruise control, idle speed, It all happened at the same time...

 

thanks for all the advice ! great forum
