Hi all, First things first. This is not a joke. It really happens. My Sons girlfriend has a '94 Blazer that wants to shock you when touched. It just started doing it recently. It doesn't happen all the time. The shock isn't bad, more like a static shock. It can happen while running or when shut off. This has me stumped. :confuse: I wouldn't think a short in a 12v system could cause this? Has anyone encountered / heard of this before? Any help would be appreciated. Thanks

Strange...

Does it only shock you when it's running or also when it's off?

Check all the ground straps from the engine to the body and the body and engine to the transmission. They are made of braided flat bare wire and tend to corrode through. There are many ground straps and you are best off to find a wiring diagram to locate them all. Good luck.

I would start with the grounds. Make sure the body ground is good as well as the battery to engine ground. Has anything been worked on lately? Does it do it anywhere on the vehicle? Will it do it before getting in or only after your in there?

PS: looks like Geno is quicker than I am!

The wife had a Toyota Van a few years back that would do that. It seemed to go with the Humidity in the air and what clothing you were wearing. It did seem to be mainly when we opened the door. I checked all the grounds and never did figure it out except it seemed to be when the Humidity was low. We traded it for the KIA I wish we had kept the Toyota.

Bill is right. Both our truck and car will do the same thing, when getting out of the vehicles. It's due to the humidity in the air. You should notice that your vehicle won't shock you, say after a rain? You'll go nuts trying to find a solution, on something that mother nature is at fault for.

Dad's old Yukon does that. The only way I could get around it is to hold a finger on one of the screws that holds the arm-rest on the door while getting out.

Sounds like static electricity, so it would depend on what clothing and shoes you are wearing, get into the habit of putting your hand on the doorframe before your feet touch the ground when you leave the car, that releases the charge slower, also be carefull when you fill with petrol..
Years ago they used to sell rubber strips that you hung under the car to get rid of the static, at least i think thats what they were for..

Did anybody ever try using the antistatic spray on the seat covers? It gets my wife regular and it rarely zaps me. She thought it might help, but I didnt get around to trying it yet.

I would also guess static shock. My wife had a car like that, I think it was a Toyota. I finally started just holding onto the door the entire time while I got out, that kept me grounded and I wouldn't get shocked going to shut the door. Have you added seat covers? Or bought new clothes? Either might suddenly cause it, or possibly not using fabric softener in the dryer causes clothes to be more static prone.

Does it have a converter from 12v to 110 for camping equipment wired into it somewhere? Once came across a van that would bout knock you down that had gone thru several owners. Somebody had the converter put in and had a cord to some appliance, we figured a small fridge. Anyway the appliance was gone the cord was under the carpet and when it got wet by the back doors BINGO !
Have had lots of vehicles that will give you the static shock getting in and out, some seats/interiors seem more prone to that, but clothing you have on and the humidity as already mentioned are the main culprits.
Good luck !
