1995 Jeep Cherokee Headlight Problem

Hi,

I almost have the same problem like the person who has a jeep cherokee on the forum. My problem is just a tiny bit different though. When I pull the headlight switch, nothing turns on except the parklights. But when I hold on to the highbeem/wiper switch, the highbeam turns on only if you hold on to the highbeam/wiper switch. I check the fuse and it's ok. Don't know what to check next except for the switch itself. Just want to make sure i'm on the right track.

Thank you,
Ric
