On my 1975 F-100 the drivers side vent window leaks some air. What is the easy and cheap fix ? The rubber looks good.

Also I have heard some folks talk about vent window locks but I can't find any for a 1975. Where should I be looking ?

 

Well the cheapest fix around is to place a nickle between the vent window frame and the vent window latch. This costs 5 cents.


What the problem is is either the latch on the window is worn out, and you can fix it by replacing the latch, or the post that holds the latch on the window is worn out or bent to where it wont let the window close with enough pressure to seal. These problems can be caused by wear like stated above or someone tried to break into the truck before and bent the post that holds the latch handle on.


Now you can fix it proper by either replacing the latch handle, if that's the problem, or by replacing the vent window frame.

If you replace the vent window frame I would get one out of a 1978 or 1979 because they had locking latches and are more secure than the older ones without. But you would have to get the latch handle with the push button as well etc...

Another way to try to fix it is to take the latch handle off, and try to bend the post on the vent window frame back into position, or bend it back toward the door window to where the latch will close with enough force for the vent window to close without leaking. This is tricky though cause the post could snap off the vent window frame and thus costing you a new one. However if you plan to buy a new one to fix the problem anyway, it wouldnt hurt to try.


hope this all makes sence, and hope it helps.

 

I like cardboard myself. I folded part of the box that a thermostat came in to wedge under the latch. Works good so far, no more wet carpet after a rain.

 

My vent window latches are so bad that it takes 2 pennies in each (4 cent mod). Works though.

 

Thanks for the info. The drivers side is bad enough for 2 nickels 10 cent mode. But the passenger side works perfect.

I guess if I want the locking latch I have to change out the frames to the 78 or 79 ?

 

Pep Boys/JC Whitney used to sell a device that hooked into the division bar, and then attached to the vent handle.

These devices are rare today, since vent windows have gone the way of the dinosaur.

Check online sites for Pep Boys and JC Whitney...maybe they will still have them listed.

 

i dont ever use the vent windows in any vehicle i own,so i took black rtv silicone and sealed them shut. they dont leak,they dont whistle.not so good if you want to open them. i never have have used them,i dont care for them,so that worked good for me.

 

Down here with 100 degress summers and no a/c you need all the air flow you can get. I could always use duct tape.

 

with duct tape you could fabricate some big scoops to add on to the windows to force the air in .hard to see out of though.lol

 

I found some aftermarket vent window locks at James Duff and only 5 bucks a pair. Check them out-- http://www.jamesduff.com/overstock.asp I think I will try a pair.

You can get these at Oreillys auto parts

 

New rubber and they still leaked air. :/

The handles are made of zinc it's a soft -and- brittle metal.

Since the handles are fine other than being bent (don't try straightening them or you find out why metallurgists call zinc "brittle";) I've been thinking about drilling them out at an angle and bushing the hole so they pull the vent window up where they did, when they were new.

What do you think? :)

Well if the handles themselves are bent, buying a new one would remedy that.

they average 20 bucks.

 

The handle won't be the problem.

The problem is the area the roll pin fits in.
After years of turning that areas become worn and loose.

Combine that with a truck being broken into at least once, it's a recipe for leaking air and a loose fit.

 

I actually agree with you Dennis.

That is the most likely reasons.
