most likely you have a vacuum issue. when you open the throttle engine vacuum drops. check under hood for leaks, there is also a vacuum storage canister inspect that as well
It's the driver's window defogger
drivers door has a switch for each window
I was looking at the 2004 Ford Freestar Owner Guide and it shows that the SINGLE switch for the power vent windows is located on the dash ( but not where on the dash , not much help ! ) The switch has " VENT " on it
A vent window on a Blazer? Wow, it must be an old one. Need to know what year you have.
should be the same door and yes you should be able to eliminate the vent window as it just bolts in the door, I didn't think a 68 had a vent window.
the hazardlight switch is where the blinkers flash,take the vent out under the hazards switch then reach up in there behind the haz. switch
I believe, if its like my GMC Jimmy, that the latch is connected to the vent window and has to be replaced as a whole assembly. I recently broke my vent window and got one from the local junk-yard, complete with latch. Now my problem is drilling out the rivets that hold the latch to the frame under the inside plastic, and the rivets that attach the front side (leading edge) under the weather-stripping to the inside of the door jamb.
All fuses are in the under hood fuse box. The lid is labeled.
Check for a vacuum leak either under hood or under dash Check the operation of the vacuum controlled motors under dash Check the operation of the selector switch Defrost is the default position for this system
take inside door panel off and the vent window is bolted inside the door as it also I believe acts as the front window channel.
Switch on the center dashboard that says 'vent'.
There is a switch that allows you to open and close the Lincoln Navigator rear side windows. The switch is located on the overhead console.
