Electrical Problem

Hi all. First time posting here with a problem. I find that all my questions have been already asked and answered so all I have needed to do is search around, but this one has me stumped. I'd appreciate any help.

My 99 TJ has 26k miles on it. I have had the usual issues with pulling the instrument panel and fixing the "no buss" message, but recently I noticed that the radio has been dead when I start it up and then comes on after a while and works. Now my turn signals AND wipers are dead. I read about messing with the hazard switch but they work just fine. Can anyone think of how these three things are related? Checked fuse block in the dash and under the hood. Meter shows no power on either side of the fuse for radio, signal and wipers, so I assume it is harness somewhere? I have everything pulled apart and can't find any good reason. My hunch is somewhere on the column. Ignition switch? Bad turn signal switch AND wiper switch seems unlikely... any ideas at all??

Thanks for a great resource!

Well, I am at a loss. I took the dash completely down, traced all the harnesses, checked all the connectors and re-seated everything I could find, and still no luck. Does anyone happen to have a wiring diagram and could tell me whether the turn signals, radio, and wipers are on the same circuit? And could the common denomenator be the ignition switch somehow?

I hate to take it to the dealer because I am not sure they are going to be any better at this than I am. Will something like this throw a code that might help narrow it down?

Solved!

For the next guy with this kind of trouble, I found the problem.

After an entire weekend with my multimeter, it occured to me that the only thing the turn signals, radio, whipers, and probably a couple of other things as well is the ignition switch.

When you turn the key, current to those things are interrupted while starting and returned when the key turns back to the run position. Wear, grease, and corrosion inside the switch was the culprit. I took the switch apart (not for the faint of heart), cleaned all the lithium grease out (why lithium greas inside a switch?!), cleaned the contacts everywhere, and put on dielectric grease instead. Works like a champ again.

Any issues in taking the switch apart and putting it back together? I have the same problems with radio and turn signal. Works fine if you turn th eswitch to AIX but not shen you start the car.

I have a problem with just the wipers and the wiper fluid not working everything else seems to be working fine. I did take my dash apart to run some new wire to my switch panel but check all the connections in the dash and under the hood checked all the fuses. Any suggestions??

That was an excellent bit of troubleshooting. I've been troubleshooting electrical/electronic gizmos since the sixties and some can be nightmares to isolate down to the exact cause of the problem. The worst electrical problems are the ones that just go away without you ever discovering what was wrong because you know it's just gonna come back later at the worst possible time.

Nice job man!
