If parking and dash lights work: Maybe bad bulbs (double filamented) Bad socket? Bad ground circuit?
check the fuse
I had the same problem with my 1997 Grand Cherokee and it was the dash mounted automatic light switch. The problem was also solved by turning the headlamps on manually.
Just replaced the headlight bulbs in a 98 Grand Cherokee that had the same problem. It had the wrong bulbs in it. It had 9007's in it. Calls for 9004's.
Try replacing the turn signal flasher
this sounds like a fuse or 2. that's where i would start.
No, the XJ Cherokee does not have the same heater box as a WJ Grand Cherokee.
It could be a fuse or yes a short.
