You may be right about the wire. I would recommend to check with wiring that goes to the solenoid on the transmission (I reckon this is automatic) first as this is directly related to the shifting in gear. It could be a faulty wire or a faulty solenoid. Check as well the ground wires. Other sensors that may be related to this is the velocity sensor which is found in the engine, most especially if you get the problem when after shifting you start to move. If you see other wires on the tranny, check the integrity of the wire and the connections. You may have wires that go back to the dash that you may have to look at.

Personally, I'd take a close look in area where steering column rotates when shifter is moved, to see if any wires bared or damaged, if it only happens when shifter moved. Check for any wires near shifter linkages at transmission as well and try to follow wires from column to transmission where they come out of firewall area as well. Doesn't matter what gear does it?

Sport fuse


did you check all fuses? yet? in both boxes?
first off the schematic (516pages) is here.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service
so you look any time and see why.
ill direct you to the pages.
the radio too can be complex. ext. amps. ill assume its 100 % DEAD
ill do radio dont play in run pos. of ign. sw., (easier)
there are 3 Cherokees, gas, desiel and export. so> and ENGINE! size
so every page is repeated 3 time. you sort that
6 fuses involved here, just for the freaking radio
but fuse 17 is the key fuse. see that. and the marking
RUN-ACC A31 , in JB (bad A31 power feed is the prob)
fuse 17 marked, X12-16rd/wt
fuse 18 kills windows. and is A31 feed too.. hummmmm
are both fuses blown, might check that..?????
so we look now at A31 (fuse 17 and 18 measure 0ohms with meter)
A31 goes to the Ignition switch, USA RHD GAS car, is most
complex and the first section of the switch has a pin3 to pin4
jumper. this jumper allows A31 power feed to reach the things
you find are dead. see page 8w-10-15 or pdf 35

see pdf page 240 for radio wires.
so what is wrong, i dont know,
but my voltmeter will tell min in 1min flat
got 12v on the A32 feed?
yes, then F17 -18 blown.
if not the jumper is bad in the ign. switch

Sounds like your on the right track. I would check for loose wire connections around the fuse boxes. Pull any fuse that has to do with the ignition or ECM/PCM, as these do corrode and loose connection. I would not rule out the ignition switch either, as the problem you are having is intermittant and switches are bad for intermittant problems. They heat up and loose contact, and regain contact when they cool down, and usually in a couple of seconds.

40 amp ignition fuse blew. I replaced the fuse and now the lights all go on when the key is turned on but the vehicle will not start...or even try to start. The battery is fully charged.


The 40 amp maxi fuse in the underhood junction block (According to the information I have, there is only one 40 amp fuse in there..) goes directly to the ignition switch. From there, it goes to the buss bar in the Instrument Panel Fuse Block where it feeds several smaller fuses. It also feeds the starter relay in the Underhood Fuse and Relay Center.

My biggest concern would be: What caused the fuse to blow in the first place?

If you get nothing else from my preaching, get this:

Fuses don't blow for no reason....ESPECIALLY not a 40-amp Maxi Fuse!

I can't count how many times I have heard people say: "It's JUST a blown fuse." WHAT???

I have been at this for 35 years and I can tell you that blown fuses are reason for major concern in my book. That 40-Amp Maxi Fuse just saved your truck from burning to the ground and you need to find out why!

The only way that fuse is going to blow is if there is a direct short to ground between the Underhood Fuse and Relay Center and the Instrument Panel Fuse Block (The only "component" between these two is the ignition switch.) or if the secondary side of the starter relay circuit is shorted to ground. The secondary side of the starter relay feeds the "S" terminal of the starter solenoid. (at the starter)

I think the first place I would look for the problem would be the circuit between the starter relay and the starter. It is likely to be shorted against the exhaust or engine block. If this is the case, it most likely fried the starter relay in the process. (which is why the fuse no longer blows and the engine no longer starts)

Aftermarket remote starting units are also usually tied into this circuit. If your vehicle has one of these, it could very likely be the original source of your problem.

At any rate, there should be no rest, truck running or not, until the reason for the blown fuse is found. You will most likely get the truck running in the process of locating the reason for the blown fuse.

2001 cheve malibu. The Automatic lights, fuel guage, power windows quit working. The radio comes on when you turn off the switch but goes off when you turn it on.


It sounds like a short in your ignition switch. I assume you engine will not start? Check your fuses because if it is a short it should have blown a fuse or you would have smelled burning isolation from the wires. If you find a fuse blown it could give you a starting place to start checking. If the ignition fuse is blown it is in the ignition, wiring, starter or ignition key switch.

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

1994 GMC Jimmy not switching gears


1994 transmission is all electronic shift so if you have a blown fuse you will likely start in second gear and never change, also when you let off the accelerator pedal the engine will return to idle rather than stay reved up till the vehicle stops. I would check your fuses and any wires in the area you worked while addressing the coolant leak you could have knocked a wire loose. also check the vaccum line going to your map sensor on the passengers side of engine beside the throttle body.

Electrical problem


Sounds more like electronic ignition switch. Coil or voltage regulator would display loss of power during acceleration, power surges (fuses blown).
