How long can you leave the 4X4 engaged while driving home in the snow in a 1999 GMC Suburban K1500 the manual says not to use it for long periods is 2 hours too long what is best?

Hi; 2 hours is quit a long time if your driving on the highway, It could lead t0 other damage to the transfer case. If in town driving and you are starting and stopping a lot, It may not seem as bad but remember to take out of gear before stopping at night so it don't freeze in gear.

Where is the orifice tube in 1999 gmc suburban?

Many GM vehicles put the AC orifice tube right after the condenser coil. It would typically be near the bottom, almost connected to the condenser. My '99 Suburban AC orifice is located in the line that runs across the passenger side inner-fender. There is a union very close to the innermost edge of the battery tray. Break that union (after relieving pressure) and you will find it there.

How do you drain water in the fuel in a gmc suburban?

Have you tried using gas line antifreeze? That will help to remove some of the water in the gas. The best way to make certain all the water is out of the tank is to siphon the gas out, let the tank air out and re-fill the tank with gas from a station you know does not have water in the gas.

What the pressure reading should be when recharging the AC on a 1999 GMC Suburban?

NOT COMPLETELT SURE OF THE PRESSURE ITSELF, BUT THE GM DUAL AC SYSTEM IS DESIGNED TO HOLD 4 LBS OF R134 REFRIGIRANT. MANY OF THE AFTERMARKET KITS AND ADDITIVES WARN ABOUT EVER PUTTING MORE THAN 36 OZS INTO YOUR AC SYSTEM, BUT THE SUBURBAN AC TAKES A FULL 64 OZ CHARGE. YOU WANT TO GET YOUR PRESSURE TO THE POINT THAT WITH THE COMPRESSOR RUNNING, YOUR LOW SIDE HOLDS A 30 TO 40 PSI CHARGE. IF AT ANY TIME YOUR LOW SIDE LINE DROPS BELOW 25, SYSTEM SHUTDOWN WILL OCCUR.

Why don't the 'daytime driving lights' work on a 1999 GMC Suburban anymore?

Make sure your parking brake is all the way off. If you notice, whenever you step on the parking brake, it turns the driving lights OUT. Even one click on the parking brake may be causing them to not come on. Otherwise check your fuses and there is a relay for the running lights also. Check that as well. Check the DRL diode. It is located just left of center under the dash. Has one screw holding it to the cross bar; kind of a pain to get to, but fixed the problem.

When I crank my 99 GMC Suburban it starts and immediately dies The security light also stays on.?

The Passlock security system is the problem. Should be recalled. Go here http://newrockies.com/?ap_id=craigpeate for a module to bypass the system completely. The resistor workaround at the key isn't always the only problem. I tried it on my 99 Suburban and it didn't do any better with the resister bypass. You need to eliminate the entire security system. Buy the pro module for $179 plus shipping and save yourself the hassle of dealing with it ever again.

How do you disconnect automatic door locks from 1994 suburban?

On some newer GM vehicles you can disarm it. But I do not know if this is even possible on your Suburban, and really think it is not possible to disarm the auto lock feature on this model. Have you looked in your owner's manual? If it is not listed there, you may have to access a shop manual. Call you local GM dealer for advice.

What causes the automatic door locks to lock and keep locking by itself an will not unlock in a 99 gmc surburban?
