Post by: gotomgo on October 13, 2010, 10:40:06 PM
87 xr7 digital dash . the displays work on left side you just have to squint to see em they dont light up. is this a bulb problem or circuit board problem? was gona pull clucter and take it apart to see but figured id ask and save my self the time if its a cluster problem not a bulb problem.and its a good excuse for some autometer gauges

More than likely a bulb problem .

X2. Does it light up correctly when you turn the headlights on?

Also, chances are, if one bulb is blown it can make that whole circuit non operative... ask me how I know ;) And... even if the bulb(s) don't look blown, dosen't mean they(it) aren't. If that's the case, you can pull all the bulbs in that circuit and continuity test them to make sure.

nope turning the lights on does not affect them . they stay very dim like there not lighting up but if i squint i can make out the gas gauge and temp.being digital i wasnt sure it had bulbs or it was something soldered in the circuit or something dumb

Replace with 194 bulbs I believe, the stock halogen ones will just burn out.

The LCD (I beleive thats what it is) will be there, it's the lighting that makes it more visible. Just pull the cluster and check for burned bulbs. And like I said, one blown bulb in a circuit could make that whole circuit not light up.
