Are you certain that you are having Vapor lock ??
I haven't seen a true case of vapor lock in years...and i own a shop.
Vapor lock (also called percolation) occurs when the gasoline in the fuel line boils. the fuel must get very hot for this to happen.
Usually it happens on a hot summer day and the fuel line is placed too closely to an exhaust manifold.
In almost every case of vapor lock i have ever seen, the car was not fuel injected but carburetted.
The cure is to re-route the fuel line away from heat sources under the hood.
But i must say that i would be surprised if you have an actual case of vapor lock. It is rare.
I just figured out my Bronco 2 is vapor locking. Going to insulate the fuel lines tomorrow.
Check the main 30amp fuse in the fuse block under the hood. If you do not use the correct amp fuse the door locks will not function properly or at all.
Bad switch?
no............ unless you have a aftermarket alarm system of some sort
That would be the Ford F-Series pickups (F150, F250 so on and so forth) The XLT was a package that had power windows and locks (conscidered a premium package)
will 1996 f250 rims fit a 1999 f250 bolt pattern
This little feature is just one of Ford's bright ideas. Eventually you'll want to disconnect the electric door locks.
no
No.
yes
Could be broken wires in the harness between the door and the body (where they bend every time the door is opened and closed). This is often seen with high mileage vehicles.
Yes you can
