speedo/tach drop
while driving around the other day my wife noticed that the airbag light came on on her dash, a few seconds later both the speedo and the tach went down to zero. no other gauges were affected. after about 5 secs at zero the airbag light went out and the gauges returned to normal. all this happened a few more times on different trips. the jeep drove as normal through this. there seems to be no pattern or any other indicator as to what would cause this. any idea on a first step. the haines manual wasn't very helpful.

my 98 Cherokee has been doing the exact same thing on and off for about a year now...I ended up pulling the dash out and noticed the connection to the gauges was a little loose...just tightened everything up best I could and haven't had it short out on me yet since I did it last week...don't know if I've cured it or not...will let you know if it happens again
