I drive a '96 E150 with front and rear air. The other day the front blower suddenly quit, while the rear air (same control panel) blows cold.
Replaced the 60amp blower fuse under the hood, still nothing.
Slammed the door getting back in, and the fan came back on, but after shutting it off, no amount of door slamming helps.
Since the fan works on none of the speeds, should I first look at the switch on the dash, or the resistor?
Thanks in advance.

 

My 95 Mark VIII had this problem. Turned out it was a generic problem with many Marks. My problem (the Mark VIII problem) was a short wire that connected to the fan motor. The connector on the end that plugged into the fan motor evidently was a little loose and it would burn and start loosing the electrical connection. Since your van is a 96, I would suspect the problem may be the same. To get to this wire on the Mark, I had to lower the glove compartment. The wire was only about 10" long. The local dealer kept this wire in stock since it was replaced so often. I recommend you check yours.
