Hello,

the first thing I would look at is the ignition switch. Smell it and look for any burns or shorts in the wiring.

I would remove that 40 amp fuse and replace it with the original rated one. The entire circuit is designed around a certain amperage and by using a larger fuse, you can damage something else.

Putting in a bigger fuse could lead to a car fire. I agree it sounds like an ignition switch.

Do you have some aftermarket stuff in your van? RAP is for retained accessory power and in no way should it be blowing a 40 amp fuse. Removing that fuse will not affect the operation of your van while running. If you remove that fuse, do you still have the same problems.

That's a good question. What electrical things have been added to your van? Remote starter, alarm, stereo? Any of these, imprperly added can cause major headaches.
The ignition switch is where the key goes, in the column.

Possibly. The RAP fuse would control stuff like an alarm, power door locks, power door windows, power seats, etc. Absolutely nothing that would pop a 40 amp fuse. Did this problem start after you did the tune-up? Maybe something didn't go in the right spot when you put the doghouse back on. That's definitely worth a look. Hopefully its nothing permanent.

The ignition switch is not were you put the key. That is the ignition cylinder. The ignition cylinder is connected to the ignition switch by a rod that travels thru the steering column. The ignition switch lives at the end of that rod on top of the steering column under the dash.

Just wanted to ask a quick question here too... I am having a few electrical problems with my 98. My doors will not unlock, you can hear them try, but, they don't actually unlock. My back glass on the dutch doors will unlock, but won't open. Also, my windows will go down about 2-3 inches , then stop, if you let it sit for a few minutes, they will go down another 2-3 inches. I have checked all of the fuses and relays and all seem to be good. Was wondering if the ignition switch could possilby be causing this too. I kinda thought of it before I got on here and this thread makes me a little more curious. Thanks in advance for any help.

Brand,

Tough first post. Welcome Aboard.

Pull the door panels and inspect the wiring in the door jam area.

Again, Welcome Aboard, Jim

The power lock actuates two rods, each rod goes to a latch on the sides of the rear hatch. One of the rods may have come off of the lever in the center of the door. Take the pull down handle off and have a look see.

I wish i had hear your advice before. I put an aftermarket cigarette lighter, after trying to use it with one cig, a fire begins inside my van, it was a real nightmare, hopefully was extinguished. Had to disassemble the entire panels and dash to find the short caused by a greater cigarrete Amper and chinesse fuse. never again!!
