Probably the blower resistor. Next to the blower motor, usually a 4 wire connector.
#843 of 1492 Door won't open by gvoigt Feb 17, 2004 (3:46 pm)
I had the same problem, it turned out to be the latch mechanism was totally fried. Had my edlerly father in the truck and he was trapped inside, luckily we were able to get him out the drivers side. Mr Goodwrench said it was a common problem they had seen. They had to disassemble the door enough while closed in order to release the latch to open it to repair it completely. Took about four hours. Waiting for the drivers door to do the same thing.
#844 of 1492 thank you by bip44 Feb 18, 2004 (7:05 am)
i appreciate your help alcan...how are you on brakes?...ha ha ... the last two days my emergency brake suddenly engages while i was backing up...i pushed the e-brake pedal down and puled the handle, but it was still engaged...then it just lets loose.....could this be a result of low brake fluid level perhaps?
#845 of 1492 I'd say the caliper by rayt2 Feb 19, 2004 (9:06 am)
is hanging up for some reason or the p. brake cable is getting stuck within it's protective cover (water/freezing). You'll need to get under there and have someone work the parking brake to see what's happening. If frozen get out the wife's hair dryer and thaw out the cable housing.   Ray T.

A friend of mine had the same problem in a 96 Jimmy. I got in the truck with him to see if we could replicate the problem. It turned out he was not letting the engine decelerate before trying to engage the 4wd. Thus the the transfer case was trying to shift while the engine was still under load. He pretty much was frying his transfer case. I told him to wait 1-2 sec after pedal release prior to pushing the 4x4 button and he has not had a problem since. I hope this works for you. If not I would insist on a whole new transfer case.
#847 of 1492 update 2002 gmc sierra 4x4 problem by mattstel Feb 27, 2004 (2:19 pm)
I finally got the dealer to replace my transfer case and guess what, it fixed the problem. Too bad it only took me three times to get them to fix it. Thanks for the advice.
#848 of 1492 Reply to post 717 engine noise - OD shift points by z71jim Mar 07, 2004 (10:47 pm)
From Post #717 You state that your 1999 Z71 OD engages at around 40mph and that your motor sounds dead.   As you know it is dead, turning around 1000rpm with the OD engaged is silly, I wish GM would wake up.   I have a 1999 Z71 Silverado 5.3, 4x4 XC. I ran across a GM TSB that fixes this. It absolutely turns the truck into a very driveable machine. The TSB had to do with "drive-line noise", but it moved the OD engagement to around 54-56mph. Its beautiful. It lets the torque convert do its thing around town. I noticed no impact on MPG.   The same issue/solution exists for 2000, 2001 (not sure for 03,04) trucks. I have a 2001 Suburban same drive-train. Unfortunately no TSB for Burbs. Its even heavier and with 40mph OD engagement at 1000rpm, its a real dog around town. I wish GM would move the OD engagement setting for Highway operation and let the converter work around town.

Have you thought about getting a a superchips type tuner that can move shift points? Might be able to up your od point to where you want it. Plus you could use it to add a little extra power and things.

Just leave the shift lever in 3rd gear around town and it will accomplish the same thing.
