Hey guys, got a quick question. Is it possible for the ignition switch to be going bad causing no power at the blower motor fuse? Like everything is working correctly on it except the blower motor and radio actually. Today I checked the 25 amp fuse under the dash and it was dead. My ignition switch has been bad for awhile now as in it wouldn’t go to the locked position and allow me to remove the key. After fooling with it for a bit I actually got the key to turn backwards and remove it. It was very stiff and gummed up but then I turned the key forward to start and the blower motor came on and was fine but after turning the key back off and trying it on again later it was dead again. So is the hot being sent through the system then back to the fuse box under the dash and its somehow not making full connection in the ignition switch? This is the radio and blower controls… with a test light everything is dead in the blower control circuit behind the switch.

 

Without checking the wiring diagram I can't be sure, but that sounds about right.

Here's a good principle to follow: fix known problems first.

If you know the ignition switch is bad, fix it. Simple.

THEN see where you are with your radio.

 

How are the turn signals and radio?

Likely the big brown wire is burned at the ignition switch. Mark makes a good point.

 

I cant comment directly on a '92, but '94-96 have a ghastly habit of burning up ignition switch as full current goes through it, this was rectified for '97 and later

The pre-emptive solution I adopted was to relay out each fan speed, annoying but necessary imo, as eventually the fan will pull too much current, and will smoke something, hopefully a fuse

 

yep, blinkers and windshield wiper aren’t working either. Just found that out this morning.

 

so its definitely something in this line I think. Today I took the steering wheel off and started getting things loose for me to get the blinker control out. After removing the lock cylinder and moving some things around a bit my blower motor, radio and blinkers all started working again lol. I’m going to go ahead and replace everything while I’m there but Indefinitely think the issue is in this area. Also, my lock cylinder seems to work fine now that its out of the column. It seems that the parts internally inside of the column is whats causing the stiffness perhaps. Like the grease inside is so old and dry that its causing a lot of drag. Can anyone confirm this on these jeeps?
