Cylinder from floor

I have searced for over an hour and cant find what the cylinder on the driver side floor is for? Its on a 71 c10. I just got it and trying to figure out what everything is for. It looks kinda like a fuse and its position on the left side floor of the driver side kinda below the emergency brake?

What is it? what does it do? can it be removed?

Re: Cylinder from floor

You mean the Headlight Dimmer Switch???

You click it with your foot for high/low beams. Each click changes it from low to high to low to high to low etc...

Re: Cylinder from floor

It works by stepping on it, waiting for it to click, then releasing. If you have ever owned a lamp with a floor switch.. Its the same thing. Its for you high beams

My thoughts Not laughing at you but laughing with you.

But it is a fair question.

By the way when did they stop using floor dimmer swiches? I remember my Dads 65 Mercury Comet has the windshield washer switch on the floor also. Those were the days

Re: Cylinder from floor

Wanna hear something stupid? The driving position in my 65 mustang is dang near perfect for me. My wrist reaches the steering wheel just right and I can very comfortably reach the brake/gas pedals, but for some dang reason I CAN NOT reach the dimmer switch. I have to actually scoot down in the seat and stretch my foot out, so I just drive around with the High beams on They're not bright at all, at least until I do the headlight upgrade to it, and I'm not too short, 5'8".

Funny story. My wife had no idea what a dimmer switch was. I told her to "watch this" and I smacked my dash and the headlights magically switched from low to high. I smacked it again and they switched back. I told her to give it a try and they switched again. Kinda freaked her out. I said it was a wiring bug. What she didn't know was I was hitting the dimmer switch with my foot. I had fun with that for a few weeks...

I use to do the same with Dad's Mercury Comet except the windshield washer switch was on the floor. I would have the kids hit the dash and then the washers would start to squirt water. It really freaked them out. Boy were those the days. Thanks for the memories

Re: Cylinder from floor

Some older cars had 3 switches down there. Dimmer and a switch for overdrive where side by side. The third one was actually a pump you stepped on to squirt washer fluid on your windshield.

Re: Cylinder from floor

Wait until the key doesn't turn to start.There were several ways that worked,the easiest to find being a button on the dash.probably the hardest was on older GM trucks(maybe some cars) where there was a "Dimmer style'switch under the accelerator.You had to floor it to crank the engine.

I hope none of you young guys run into an Edsel with all those buttons in the centre of the steering wheel. Truely a typewriter shifter.

Re: Cylinder from floor

dimmer switch on the floor and key in the dashboard, two criteria of a cool vehicle.

key on the dashboard is coming back (if you can call it a key) but the floor mounted dimmer switch is a thing of the past.

Re: Cylinder from floor

To this day... when I jump in to my '06 Silverado I still tap my left foot... looking for the dimmer switch. Then my brain slowly remembers to pull on the blinker doo-hickey switch arm thingy. It's the newest rig I've ever owned...

Re: Cylinder from floor

I'll bet a bunch of you have never seen a seat that moves out to you and swivels to make it easier to get in. Steering wheel pivoted off to the right at the same time. You sat down and the seat slid back in, swung back to centre and the wheel locked back in the centre.
Any guesses at what car?

That would be a thunderbird. Ever tried to find a vacuum leak in one of those? Everything runs off vacuum in those suckers! Must be 12 miles of vacuum lines behind the dash!
