Heater lights flashing ..alternator belt broke,battery went dead, when replaced,heater lights started flashing and won't go out.. 1998 dodge caravan 3l

Was the battery checked, if not check if for any dead cells., and make sure its taking a charge. A bad or weak belt tensioner may be causing the problem.

More details please, is enough gas? Is the starter running? And more...

Same problem with my 98 grand caravan! Turn heater on high with air directional toward your face. Press & hold top back wiper button & bottom back wiper button (1 button between) until all buttons light up. Release buttons. Then it will go thru reset process. After a few mins. If top button is still lit up, repeat steps again. Found instructions written in back of my manual. Worked like a charm!

I'm betting you routed the belt incorrectly.

u got a short or something.

sounds to me like a siezed up ac unit.. it would not spin while all other pulleys spin... thus causing the broken belt.. hope that helps you

check for loose or corroded wires from alternator to battery.

is the alternator dead? or the starter? check these two and therein you should find your solution

Like you said, battery may be flat. You can check that with a multimeter.

Next check the alternator. Faulty alternator leads to uncharged battery.
