#286 of 354 Should my drivers side window stop working when its hot outside??? by redcurlz Mar 06, 2009 (3:24 pm)
This sounds wierd but it seems that when the temp outside gets above 75deg my window wont open. It's electrical so can I just replace the switch on the door or is it more complicated you think? Thank a bunch for the input.

Replying to: redcurlz (Mar 06, 2009 3:22 pm) That definitely sounds like the place to start. Usually when several functions on that lever act up together, replacing the assembly cures it.   kcram - Pickups/Wagons Host Replies to this message: akjbmw (Mar 08, 2009 11:25 pm)
#288 of 354 2007 GMC Duramax 3500 by seabeemax Mar 08, 2009 (10:08 pm)
I have owned this truck from the start and it was getting around 20 MPG not pulling,I have a 38 ft 5er and in the past I could get 14 MPG give or take. After leaving Utah and heading to Salida Co when twice this thing over heated to the point both the engine temp and the trans temp went all the way over,it boiled out the antifreeze to the point I had to add a half gallon. This truck has pulled the Mountains two to four times and never had a problem. Since this happened my fuel milage has gone down to about 11 to 14 empty. GM said they don't find a thing wrong,so if I leave AZ. pulling my 5er what the heck you think I'm going to get. Trading it is the last thing I want to do,any ideas??????????? Is it the computer its got me. Seabeemax

Replying to: kcram (Mar 07, 2009 3:42 pm) A couple years ago, my '98 K1500 Silverado developed a wiper issue. I seldom used the cruise control (can't go anywhere without up and down hills here in the Sierras) so I don't know if it was affected. The fix for mine was the controller "black box" that is attached to the side of the wiper motor. Get the box from Napa (or equivalent), remove the wiper assembly, replace the part, and reinstall. No more problems. With my new truck, I will have to use a ladder to do that...

#294 of 354 2002 Silverado 4x4 under hood 40 amp ?stud 1 & 2 Fuse? by pleasehelp5 Mar 23, 2009 (3:05 pm)
Anyone know what these fuses go to? I only have the diagram on the cover and it says stud#1 and on the other end is stud#2.They're the big colored fuses. I was trying to see if the fuse to my w/w pump went out, and I noticed the "stud#1 was blown. I replaced it and it's still good,but I cant figure out what it goes to. I looked in the chiltons and they got nothing. Please Help   Never mind......I figured it out. Its for the acc. power and trailer wiring feed. Thanks anyway
#295 of 354 Re: How to reset a fault code [jneal] by lester55 Mar 30, 2009 (3:27 pm)
Replying to: jneal (Oct 23, 2006 5:55 am) I was at the chevy dealer one time:) and asked how to reset a message light. He said to don't start the engine but turn on the key and step on the gas peddle all the way to the floor 5 times and then turn the key off and then on. I tried it and it worked. sounds funny but at least give it a try.
