This is a cautionary tale for anyone considering removing something from their rig before they know exactly what that something does.
I’d just gotten my van back from my mechanic. He’s replaced my fuel pump, and I was back in the business of vanlife.
I was house sitting for a friend, so I used the opportunity of having a parking spot to clean my van. I collected all the trash I’d let accumulate and dumped it into her garbage can. I was pleased to think how great my van was going to look after this cleanup.
While standing outside the van, I reached under the driver’s seat and felt around for any trash that had ended up hidden there. My hand connected with some sort of flat, plastic box. I wondered what it was. I didn’t remember tucking a box under the seat.
I pulled out the object, quickly realizing it was tethered by a cord to something else under the seat. I could hold the box in my hands, but couldn’t lift it more than a foot or so off the floor. If I hadn’t been standing outside the van, I probably couldn’t have pulled it out from under the seat at all. What was this thing?
I looked at the object closely. It was an inch or two thick, maybe eight inches wide, and ten inches long. It was constructed entirely of smooth black plastic, except for slightly raised letters on the top which spelled out “C-O-M-P-U-T-E-R.” Computer? What kind of computer could this possibly?
My van was a 1992 Chevy G20. While not a classic car, it was not a hotbed of technology either. Would something from 1992 really have a computer? Would something important to the operation of the vehicle really be stored under the seat? I didn’t think so! I decided (with no research and not much consideration) that this computer must operate no longer functioning power seat controls. Of course, neither of the seats had any buttons or knobs that might have been associated with power controls at some time in the past, but I didn’t let that detail influence my ideas about what the plastic box was for.
Anyone who’s lived in a vehicle (even a relatively roomy conversion van) knows that space is at a premium. Any little nook or cranny that can be emptied can provide a home for some more important item. I had visions of storing books under the driver’s seat if I could ditch this bulky, unnecessary (in my mind) “computer” box.
As I continued to examine the box, I found the cord was attached to the box by a plug. I simply unplugged the cord and the box was free. Easy! (I left the cord tucked under the seat, out of my way.)
Some guardian angel was looking over my shoulder that day because I didn’t throw the box into my friend’s garbage can. I can’t remember why. Maybe it was because I knew electronics aren’t supposed to end up in the landfill, and I’d decided to find an appropriate way to dispose of the thing. Maybe I had a sliver of good sense and realized it wasn’t a good idea to throw out a part when I didn’t know its function. In any case, the unplugged box stayed on the floor between the two front seats, and I wandered back into my friend’s house.
The next day I wanted to go somewhere, so I climbed into my van’s driver seat and started the engine. I immediately noticed the check engine light was on. Damn!
My first thought was that my mechanic must have caused the problem. Maybe he’d damaged something when he replaced the fuel pump. Maybe he hadn’t replaced something properly. I was going to have to call him and find out how he planned to rectify the situation.
Before I picked up the phone, I contemplated the situation further. Had the check engine light been on when I picked up the van at the repair shop? Had it come on as I drove from the shop to my friend’s house? I didn’t remember it being on. I’ve always been observant of my control panel, so I was confident I would have noticed the light had it been on previously.
I sat there and thought about what had changed since I’d parked the van at my friend’s place. Nothing really. I’d cleaned up, picked up trash, pulled the “computer” from under the driver’s seat…
Oh no! It began to dawn on me that maybe that “computer” controlled more than the movements of my chairs.
I shut off the van’s engine, then located the black box on the floor between the two front seats. Maybe this thing was more important than I’d thought.
I grabbed the plastic box and slid out of the van. I stood on the driver’s side of the van with the door open so I could reach under the seat. After some fumbling, I found the cord the box had been attached to and plugged it back in. I tucked the box under the seat, then climbed back into the van. When I turned the key in the ignition, I was relieved to see that the check engine light did not come on. Problem solved!
Apparently in 1992 vans did have computers, and they were stored under the driver’s seat!
For several years, I thought this was mostly a funny story of my stupidity that I would share on my blog someday. After all, no real damage was done, all’s well that end well, and surely I’m the only person who’d make such a mistake. Then my friend did something similar, and I knew I had to share my story as a cautionary tale.
Without sharing too much of my friend’s business, she cut some wires in her rig that she thought were unnecessary. It turned out that all of the components of her rig’s electrical system were connected and no one wire could be removed without affecting the entire system. Ooops!
My friend’s problem was more difficult and expensive to fix than mine was, but, thankfully, her rig is up and running again.
In any case, please learn a lesson from what my friend and I did wrong. If you don’t really know what you’re doing, don’t remove anything from your rig, unplug anything, or sever any cords. Maybe check the manual, do some research online, or ask a mechanic or knowledgeable friend before you start making changes that could lead to tears and aggravation.
