Have a 05 dodge 1500 the 4x4 switch an overhead console leds quit working an keeps blowing the fuse as soon as i put it in


Odd that your vehicle runs both systems on the same circuit and with only a 10 amp fuse. I'd try a 20 amp fuse to see if that works. Worth a shot, it shouldn't harm anything.

start chasing wires. Sounds like something is shorted or worse, a hot wire may be grounded out.
Good place to start is all wires headed to the started as that is a common place for a power wire to melt against hot exhaust.
(that was the case for my 99 chevy)
Check all other fuses and make sure none are blown.

Interior light fuse blows


Sounds like something is making a short circuit somewhere. First, check in each light socket to make sure there is nothing loose in them and that nothing is touching the body of the car. If that doesn't do it, one of the wires going to one of the sockets could be cut, pinched or rubbing against something enough to wear through the insulation. That is a little harder to check as it requires pulling the headliner, door panels and anything else that is hiding the wires.

My atc fuse would keep blowing I put a bigger fuse it didn't blow that but I herd a zap noise from my TCCM now my 4x4 won't work 1999 jimmy


What you have done? You Just damage the TCCM and that's why you will not manage to shift 4x4. Why this happened? Because you had shortage somewhere and you receive blown ATC fuse.You put a bigger fuse in capacity where the was stronger to blown and the fault moved to the tccm system which was not protected and blown.Ask for an expert to check and see whether the fault is easy to get fixed.

I have a 2002 Trailblazer. The 4wheel drive service light is on what should I do? The 4wheel drive isn't working at all. Can I continue to drive in 2 wheel High until I get to dealer?


Your fine to drive it on 2wd till you make it to the dealer, but in the mean time check your 4wd fuse. The 4X4 encoder motor is know to blow fuses in cold days and it's a simple fix by replacing a fuse for 35 cent then having a dealer replace it for $65.00 service charge. Good luck and hope ti's a simple fuse that has gone bad, there common to go bad when 4wd is engaged during cold operation.

I have a 1998 chevy blazer (s-10) 4.3L 4x4 it keeps blowing the #15 (10amp) 4wd fuse, if you put a 10 amp fuse in it will blow the minute you turn it on ,then we put a 15 amp in it seems to do it when you...


check transfer case electrical switch, sometime if it bad it will also blow the fuse. don't recommend you put any higher fuse than recommend, If the fuse blow there is a short some where and by putting higher amp fuse you might short or burn something else beside the fuse. if that check out than check your transfer case motor, might lock up and not allowing the motor to turn instead it short the fuse. don't drive the car, just leave it in park, put correct fuse amp back in and unplug transfer case electric switch and turn the key on (dont start the car) and see if the fuse blow; if not plug it back in and see if it blow the fuse. if that is not the case, unplug transfer case wire, and do the same and see if it blow the fuse.

Ignition problems


the expeditions had a problem with the rear wiper motor grounding out, i would try replacing the wiper motor first, as for the fuse blowing, it is blowing for a reason, fuses don't just blow. if the wiper motor does not fix you may need to have someone go thru the electrical pin point tests to find the short.
