The main fuse that controls the entire fuse box is what I found worked for me on my 2003 GMC Envoy. I accidentally touched my wrench to the left side of the fuse while hooking the negative up on my battery causing all my interior lights, radio, a/c etc. to not work. It's only $4.99 at advanced auto. Took me awhile after checking every damn fuse in the car and not finding anything. Hope this helps
Hooking up the battery backwards causes a surge that blows the engine main fuse.The main fuse is usually found in the engine bay's fuse box.
If your lucky you blow many fuses. But alot of the times every electrical component will puff magic smoke and will need replacing. Especially the Computer, Radio and Body Control Module.
you blew fuses. find them and replace then.
in cab or in engine bay, main fuse boxes.
the first step in doing electric installs is to pull battery neg lug.
if not you blow fuses.
on newer cars 1st step is get and write down NAV and radio codes.
or they will be dead. later..
you have blown the fuse or fuse. check the fuse box in the car and in the engine bay. 1995 model has a main line fuse in the little fuse box in engine bay. if it did this from the radio the radio fuse will have blown as well.
Holden Rodeo 1989 2.6mpi , start and only runs for 2 or so seconds themselves stalls, after putting on a fuel peesure gauge, fuel looked okay and slowly dropping, found the ECM relay was intermittently switching on and off, gave it a tap and the engine kept on running, relay not repairable, replace with new part. Located in the fuse and relay box on the right hand side of engine bay next to battery. Hope this helps.
there should be another fuse/relay box under the hood,usually by the battery.it mostly always has a black cover on it with push in clips on either side to release the cover.im not sure but if all the fuses are good in the engine bay,you might want to take a look behind the driver side and passenger side kick panel for more fuses/relays. hope this info helps you. take care and good luck, manny
It is recommended that the engine ECU is reset after any engine performance modifications have been made to the vehicle, including using a higher octane fuel, to accelerate the learning of any new parameters. Resetting the ECU will also clear any stored error codes, however if you have a fault with your vehicle it is advisable that these codes are retrieved rather than wiped as they may help in diagnosing the problem.
Make sure the ignition is turned off
Remove the engine bay fuse box cover
Remove the 20Amp/25Amp EFI fuse
Remove the 15Amp ETCS fuse
Wait 30 seconds
Re-insert the two fuses
Install the fuse box cover
It is also possible to reset the engine ECU by removing the battery. Please note that this method will also reset any memory settings such as radio presets, trip mileage, clock etc.
You got an open in one of the wires that feed your ipc, radio, power windows and a/c. Look around the engine bay for a worn out wire harness where there could be cut wires. Would probably be the harness that goes from the main fuse box trough the firewall, and by the way, make shure there's nothing (wires for electric brakes for exemple) that went trought the firewall's harness gromet. People have a bad habit of cutting the harness wile fishing wires trough there.
