Billowing well liner

Last week I went out for a ride with the top up and the windows open. At highway speeds the well liner fills up with air like a balloon and obscures the back window. Is there a remedy for this? Besides keeping the windows up or the top down or slowing down?

 

I've had that problem too with my LeSabre. I've thought about just putting a little weight in there like a piece of 1/2'' steel pipe or something

 

fixing the rust holes would be the best way.

on the fullsized cars that have had a plastic window replace the original glass window, you can tie a wire from the glass pulling bracket to the other glass pulling bracket passing the wire through the top well on its way between the brackets.
on an a body, i dont know if there are any available hole lined up like on the b body cars.

 

No rust holes. It's all new sheetmetal. I thought about weighting it down and then thought - with my luck the weight will fly out of the well and hit me in the back of my head, or worse - damage my paint job (nightmares!) There has to be some safe way to hold it down. I am considering some cloth straps with snaps on them in the trunk. Snap one end to the corners of the well liner and snap the other end to the floor of the trunk.

 

Quick fix. If it is warm enough for the windows to be open, the top should be down.

 

I think what Yuk is saying is that there is positive air flow from trunk...you've got air infiltration somewhere back there...wheelhouse, floor, deck lid seal...

 

The air is supposed to flow through these cars, they were designed that way. The air is coming from several areas, under the front of the back seat, the back arm rests and the piston covers.

 

but its "flowing" the wrong direction....
the air is supposed to flow from the passenger compartment into the trunk and then froward in the rear quarters and out the door jamb vents. not build in the trunk and swell the top well trying to get into the car.
drive it down a dusty road with the top and windows up and see what happens .... it wont be pretty.

bad "putty" around the trunk lid crimp, un sealed tailights (some cars), wheel wells, trunk floor, lower quareters, poor trunk lid seal.... the list goes on for possible cuprits in the trunk area.

rent a chemical fog machine and park the car in the garage out of the wind. completely fog the trunk of the car with the windows up ....
have the hood up also.
hot wire the blower motor a few seconds at a time and have spotters look for smoke escaping from these places.

it dont take much of a leak getting 50+ mph worth of air shoving into it to make problems.

 

This should be titled "How to make a mountain out of a mole hill".

Thanks, I'll find a way to tie down the well liner before I go and pressurize the car with a rented fog machine.

 

o No:Could it be that, the flaps in the vents at the door jambs are stuck? Not letting the air out? Or, maybe you could sew a bit of lead a the edges of your well liner? Sewn in, you wouldn't have to worry about them being loose. And lead won't corrode and stain the liner.o No:

 

Yes...and if it were flowing in the correct direction, the liner wouldn't billow. The fact that it does says that there is more pressure in trunk than passenger compartment. Since underside of car is high pressure area at speed, most likely there is trunk infiltration thru floor, wheel wells, drops,...
