On my 95 yj (no ac) the blower fan runs on heat and defrost, but not on vent. Is there a way to wire this so that it runs when the switch is in the vent position?

So it is supposed to run when it is on vent?

Well, I think I have seperate vents for the AC and heater that are front blowing. I don't know for sure because I can't start my Jeep. There is an elderly woman down the road on a fixed income that had a dead battery in her car. I gave her my battery out of my Jeep and I was going to go buy myself a new one today. I'll check into it when I get it going.

Um... I said I would check. The AC vents and the heater vents are seperate. Since I never use them, I don't know which ones are which. I'll check into it to see what blows from where as soon as I get a battery in it.
I have 5 total front blowing vents. I think 3 are AC and 2 are heater, but I don't know. I'll have to run it to see.

Yeah, I know exactly what you are saying. I am saying that they are seperate units. The duct work for the AC and heater have nothing to do with each other. You have no AC, but the duct work for the AC is still there. For you to use the front vents with your blower would, I assume, take some modification of the vent duct work. I understand you don't have AC, but you have AC vents.
Anyway, all I was saying in my post is that I didn't know if all the front blowing vents were for AC or if some were for the heater. They are all for the AC, therefore useless to you.
On a ligher note, I got a battery back in the YJ. Also, I may be close to picking up a 2005 TJ the dealer has. Only problem is it has been regeared very low. Also, it rides rough compared to my YJ. I know the guy that owned it, so I'm gonna get with him and find out the real story.

Maybe we need to start all over...
There are no vents in the dash. Only the two defrost vents on the top. The heater blows out of the y shaped vent above the transmission hump on the floor and out of the box located under the glove compartment.
The controls on the panel have defrost, heat, vent on the top lever, and cool and warm on the bottom lever. There is a 3 speed fan switch on the driver's side of the panel.
The fan does nothing when the top lever is set on vent. It blows out of the floor vents when on heat, and the defrost vents on defrost. But when you have the panel set on vent, fresh air comes out of the floor vents, it is just not being blown out.
What I want to do is to be able to run the blower fan through the floor vents when the lever is set on vent. Can I hook up a toggle switch mounted on the dash where the toggle switch for my driving lights is mounted - going to the accessory fuse under the dash and to the blower motor, to accomplish this? Or will it interfere with the levers that control heat and defrost?
Sorry to be such a pain. What I thought was a simple question, got very complicated.

Ok. The mechanic I spoke with said the vents were there even if the AC wasn't obviously he told me wrong.
All I can say for sure is that when I put my switch on vent in my YJ, it doesn't do anything and as best I can recall in the years I have had her, it never has done anything. I assumed it was made that way, but I could be wrong.
Sorry. I don't think I'm any help. I'm going to go see if there is enough light for me to take a picture of my dashboard. If there is, I'll post it. I think my dash is going to have more vents than yours, since you have no AC.

After consultation with Frank (keeping in mind we do not know the YJ model 
): some older model vehicles would have variable blower controls for ac or heat, but when you switched the vent lever(as illistrated in amerijeep's pic) the vent was either opened or closed....control was achieved by how far the lever is pushed over. On our CJ, the vent is opened and closed by pulling a knob away from the panel, it does not have a variable speed control for a blower.

My 94' fan does not operate when on Vent either. In the Vent position outside air is channeld through the box under the glovebox, and Not through the heater vents over the hump.
I believe the fan is Bypassed (Physically) when in Vent Mode, so running it or making it run would do nothing beneficial....it's blocked off from the fresh air.
I think this because, once on my Jeep, the flap would stick on the fresh air vent, so I had to figure out why....... I seem to remember sticking my hand as far as it would go into the vents and then moving the lever.........if memory serves there is a flap Inside which opens and closes...(i'm talking the vents over the hump)
Double check me on this though......cuz I aint the best at this stuff.

That's what I needed to know. Thanks. I put a scoop on the cowl vent in front of the windshield and it has helped move more fresh air in, but it would be good to be able to move air when you are sitting still. Oh well, the temps around here have broken and it looks like maybe we are out of the 90-100 degree heat. I will try to figure something out before next June.

I hear that.
How about a Fan that plugs into lighter?
I used one for a while that plugged directly into it, and had a flexible neck.....it did not work to well cuz it was heavy and would rattle out and fall on the floor alot.
I recently aquired another one that has a lead and the fan has a clip....so there should be more mounting options. The On Switch is built into the lead and has mounting points too. Havn't played with it yet.........but I think it should do the trick.....It's not as HOT here in NY though.

Yeah, I was just thinking about that. Or maybe I could get one of those hats with the can holder on each side and a fan like a propeller on top.NY94YJ said:
