Most likely culprit is that one or more of the (very fine) wires that make up the defrost matrix on the rear window itself are broken. The entire unit needs to be replaced. They sell the kits at JCWhitney.com or you can have a pro install it for six times the price. Another alternative is the wire connector on the side of the window that attaches to the unit. If you live in a cold area that tends to get corroded as well.
simplest thing to check-fuses!
Im gonna guess that it depends on what year it is. Mine is an 1983. The dash fuses on my particular firebird are located on the driver's side lower panel
Power window fuses for Chevy Astro Van should be under driver's side dash. If you put Driver seat all the way back it will make it easier to access fuses. On my '94 Astro van EXT these fuses are labeled power wd.
if manual, window regulator. if electric, check fuses, window switch, window motor, window regulator.
I can't tell you the exact name of the part. I believe that if you take the back panel off inside next to the rear window where the defogger connects, you will find that the part is burnt. It will be on the passenger rear. Do not confuse it with the antenna. I went to a salvage yard and got one from a used Lesabre.
I just found a fuse box under my hood in a black box with all kinds of fuses,in it there they were window fuses. what was the number and code please.?
where is the fuses for the power windows
Check the window fuses. They are located underneath the driver side kick panel. If the fuses are blown the windows will not work.
open the driver door and then there is a little panal on the side of the dashboard. take it off and inside are all the fuses. then look on the otherside of the panal and it has a list of what fuses do what
Make sure the window is all the way up. If you think it is, lower the window all the way then raise it all the way. Then try the wiper and fluid delivery system. Well Done. This worked perfectly for me.
It should be in the fuse panel with all of the rest of the fuses.
Could be the switch, or the motor itself on that window.
