1990 Ford Bronco instrument gauges lights won't come on

does radio or interior dome light work? could be faulty dimmer switch

The dome light doesn't come on but the radio does. and how do you check to see if its the dimmer switch thats bad?

need to run continuity test on the switch. first remove switch and make sure wires look ok and are connected

ok. is there anything else I can try first to get the lights to work? because i have to borrow my friends multimeter to do a continuity test.

if the bulbs and fuses were already checked out then your best bet would be a faulty dimmer switch or wiring to the switch

ok. thanks for the help. Greatly appreciated.

Oh and I was wondering if you could help me with something else too. I have tried using my 4x4 on my bronco and it goes into 4hi but it wont go into the neutral or 4low. Do you know what the issue is there? it has been bugging me for a while because I can't get it to move lower than the high setting and im hoping it isnt broken

is this the Bronco or Bronco II and you have manual or automatic locking hubs?

its a fullsize bronco and i have manual hubs. but its not the actual car thats having trouble going into 4wheel. i just cant shift the 4x4 stick into N or 4L but i can shift it to 4H

should be chain driven, have you inspected transfer case under vehicle

no i havent looked at the transfer case. but what would i look for on the transfer case to find out why the shifter doesnt move lower? and is the chain part connected to the shifter?

should have a control rod between the shift level and the control lever assembly, make sure these are connected to transfer case

well i think they are connected because it shifts into 4H and then gets jammed so you cant move the shift lever any further down. would it have anything to do with maybe some dirt or something stuck on it preventing it from moving further?

maybe or the rods may need realigned. when did it stop working? did you try shifting it into 4 low while stopped or rolling?

i tried it while it was stopped. i didnt know you can shift it into 4 low while moving. i thought you could only do that when changing to 4H. and it didnt work when i bought the truck about a few weeks ago.

but it could be that the rods need to be realigned. i will look at that tomorrow.

not supposed to while rolling thats what i was just checking to make sure

ok. well thanks for all the help. i really appreciate it. im going to try and fix those two things tomorrow
