Maybe someone had the door panel off and didn't reconnect the switch properly? The memory seat module is located under the driver seat (attached to the seat). Maybe check to be sure all the plugs are connected properly.

Trust me on this one: The only thing to do in a situation like this is Hook it Up to a Quality OVD2 Diagnostic Scanner, if you don't its just a guessing game as many things can cause this. Call a friend or family member who has a scanner and have it checked, or go to a local parr's store and pick up an inexpensive obd2 scanner- they plug into the diagnostic port under the dash on the driver side, this will tell you the source of the problem or at least point you in the right direction!

The fact that that you haven't lost coolant and your reservoir is full still is a good sign. Try these 2 things:

1.) Check the oil and see if it looks "milky" or a strange color that's not the typical color of engine oil. If it looks ok at first glance, Look carefully at the dipstick and see if the oil level appears to be over filled- you'll know because the dipstick will be showing that it's at a level above full. This indicates that water/coolant has gotten into your oil and you likely have a blown intake gasket, this is common on GM Trucks/SUVs with the 4.8L/5.3L/6.0L V8.

2.) When the engine is cold and hasn't been running for a while, pop the hood and then start it up, quickly look under the hood for any leaks- especially around the water pump S it may be the issue(and an easy fix), or perhaps a radiator/heater hose is busted/leaking(also an easy fix). Just look for any leaks, if you have a friend or family member around get them to help you look for leaks, use a bright flashlight(even if it's daytime) so you don't miss a small leak as they're not always as obvious to see as you'd think. IT's OK TO LET IT RUN FOR A FEW MINUTEA BUT ONLY 2-3 MINUTES AT MOST AS ANY MORE TIME WILL CAUSE THE ENGINE TO OVERHEAT AND THAT'LL MAKE MATTERS WORSE AND YOU COULD END UP WITH A HUGE REPAIR BILL FOR MAJOR ENGIE ISSUE(S) INSTEAD- 2-3 MINUTES IS OK BUT THE SHORTER THE BETTER, SO IF YOU SEE A LEAK FIND ITS SOURCE AND CUT THE ENGINE OFF IMMEDIATELY- DON'T LET IT RUN ANY LONGER FHAN ABSOLUTELY NECESSARY!

I just fixed this issue on a Tahoe like yours and it was the water pump, the last one I fixed was an intake gasket, more on all of this below.

Regarding the Gauge Issue: it sounds like your Temperature Sending Unit is Bad which is no big deal and not expensive- it simply communicates with your gauge to display the engine temperature.

The overheating could be a number of things but most likely is a blown intake gasket as the 4.8L/5.3L/6.0L V8 Engines In 1999-Up Full Size GM Trucks & SUV's are known for having this issue. I just fixed a friend's Tahoe with this issue, I've done it many times on these GM Vehicles- I just bought a Tahoe with the same issue.

Worst Case Scenario is a Head Gasket Blown(or both are) and your cylinder heads could be warped or cracked as we, but it's usually not so serious, especially if you didn't drive it or let it run very long at all after noticing the overheating issue.

Any good mechanic/technician can diagnose this easily by doing a few common tests like a compression test and a leak-down test of your cooling system, etc.

Don't let that information alarm you, it may not be a big deal at all and a simple fix like a bad water pump, replacing the temperature sending unit, intake gasket, or all of the above which isn't expensive or hard to do at home with some mechanical ability and hand tools, but don't attempt it if you don't have any experience doing things like this- if you have any mechanical experience and can follow instructions then your Tahoe and all vehicles with the 4.8/5.3/6.0 are way easier than most to do the various repairs I've mentioned above to!

This link will tell you and show you.
The 5th letter in the VIN will tell you
R=2 wheel drive
V=4 wheel drive.

Look under the vehicle. If it has a driveline going to the front axle it is a 4x4.

I have a 2004 Suburban and the air bag light came on. It was one of the sensors located on the inside of the front bumper. They were cheap enough, I replaced both. Take the big plastic undercover off, and look on the inside of the front bumper, on the bottom, you will find them. A 10mm socket on a 1/4 drive reached them easily. Un hook the electrical connection, unbolt, and bolt on the new ones. Then reattach the electrical clip. Here is a video https://www.youtube.com/watch?v=UlcHQ-jmm0E

The audible warning system is controlled by the audio alarm module. On base models the chimed output is produced by the audio alarm module. Power is provided to the system from the GAUGES fuse through CKT 39 (PNK). Ground is provided through CKT 150 (BLK) to G200.

Presets always go when you disconnect a radio from the power. Very few have an internal backup battery. Number one tip, always maintain power to a vehicle when you change batteries. Easy to do using a battery charger, a set of jump leads or even just a couple of lengths of wire.

Not being able to set the clock is an odd one. How well do you know your local dealership? They would take a look at setting the clock for free. The salesmen love doing that stuff.

I am Sharla Client from the USA and i am a mechanical engineer in Audi Germany. I saw your case and I have come to a point that this 1990 v2500 4wheel has no crank shifter which means that the transmission will not work with aftermarket alteration. Yes you are doing an aftermarket alteration i can say because i have also worked for a

A blinking service 4x4 light would indicate there are DTC'S - diagnostic trouble codes set . Need a professional scanner to pull these codes , not autozone or advance etc.... How many buttons on the shift selector ? Four or three - this would tell me which transfer case it has an capabilities .
The NVG 263 transfer case features a three button shift control switch located on the instrument panel.
The NVG 236/246 transfer case features a 4 button shift control switch located on the instrument panel
Both systems have a electronic control module .

SERVICE 4WD Indicator
The SERVICE 4WD message is displayed on the driver information center and is an integral part of the cluster and cannot be serviced separately. This message is used to inform the driver of the vehicle of malfunctions within the automatic transfer case (ATC) system. The SERVICE 4WD message is controlled by the transfer case shift control module via a Class 2 message.

Upon seeing this message it is intended for the driver of the vehicle to take his vehicle to a qualified repair shop that has the knowledge an diagnostic equipment to trouble shoot the problem .
These systems can set many codes an without knowing which or if any are set at all you could end up replacing parts an still not fix the problem .
DTC B2725
DTC C0300
DTC C0305
DTC C0308
DTC C0309
DTC C0310
DTC C0315
DTC C0323
DTC C0324
DTC C0327
DTC C0362
DTC C0367
DTC C0374
DTC C0376
DTC C0387
DTC C0550
DTC C0611

Your best bet , take it to a qualified repair shop .
