"Adjusting" doors

Post by cdoughty »

One of my doors has a 1/4 inch gap at top-rear. This time of year it gives a nice cooling jet on my neck. I have tried new seals, adjusting the catch, and to spring it to be a little more curved on the back edge with no success. I've been cautious about springing it because I don't want to be posting in the for sale section looking for a new door. Just wondering if anyone out there has a secret fix?

Look for a crack in the inner door skin near the latch. This allows the door to flex outward at the top. There is no adjustment. If you don't find a crack, I've heard of people installing a VW (bug) window latch in the upper corner to hold it shut.

Ours does this too . I've heard that if theirs no relief outlet for air its got to go out somewhere? We have a closed baggage compartment and I wonder if there was a better outlet there it would exit the rear tail cone area instead of out the weakest part of the doors?

Actually, air flows up from the tailcone into the cabin. Blocking that path would only help in this situation.
