90eliminator Posted March 4, 2009 Posted March 4, 2009 so my jeep has one from the factory, doesnt work, where should I start... Are these all internal or do they have any external control units...? Thanks
HOrnbrod Posted March 4, 2009 Posted March 4, 2009 Fuse okay? If so, all there is to know about clocks HERE.
HOrnbrod Posted March 4, 2009 Posted March 4, 2009 They use an LCD display, and that's what usually burns up when they fail.
tugalo Posted March 4, 2009 Posted March 4, 2009 Remove the clock and check the small instrument panel bulb mounted on the back side. I think it is a #74. thats the usual problem
SuperWade2 Posted March 4, 2009 Posted March 4, 2009 They use an LCD display, and that's what usually burns up when they fail. So if the LCD is actually showing up, just dim at heck, then it's likely a bulb and not the LCD?
Comanche County Posted March 5, 2009 Posted March 5, 2009 I have the same problem with my clock, I think it works but can't really see it. That's a great link,,,,I'm going to get started while my head is in the shop getting rebuilt. :thumbsup:
HOrnbrod Posted March 5, 2009 Posted March 5, 2009 Yes. If the display is working but dim, probably needs a new backlight bulb. They got rid of the bulb in 91 and it's much brighter.
aemsee Posted March 5, 2009 Posted March 5, 2009 I just changed the bulb in mine. It was just a couple of bucks for a pair at Advance Auto.
