I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

SOURCE: 2000 gmc sierra 1500 5.3 v8. a/c heater control problem

your heat/cool and vent selection options are controlled by engine vacuum through small clear tubes attached to the rear of your climate control interface. Other vehicles have small steel pull wires that operate the desired changes. You might try removing the trim and any fasteners affiliated with the interface/console. GENTLY pull outward and look to see if any of these tubes are pulled off or cut/damaged. Did anyone recently install a new stereo in the vehicle? If so, the vacuum tubing and or pull wires that change your outlets could have been damaged when the stereo unit was pushed into place. Hope this helps

SOURCE: My 2004 GMC sierra blows hot air out the drivers

If you've replaced the actuators and they are working.
One of the blend doors may be broken inside the heater box. To repair or replace the broken door you
have to remove the heater box. This is not a small job. The book gives 6-7 hours for the job. There is a
cheat that I've heard good things about. I guess it can
be done in a fraction of the time. You can find out
about it at I have not used it myself
but I know somone who has. And it worked well for
him. Hope this helps.

Replace air flap actuator on gmc envoy slt

Air flap or mode actuators should be located on lower drivers side (slightly up and right of gas pedal) and lower left (slightly left of glove compartment). Research YouTube for removal/installation videos. Good luck.

1995 gmc sierra 1500 actuator looks to be working correctly but i still get a small amount of air through defrost or panel when i have the slector set to floor ? blend door ?

Does the actuator make any kind of clicking noise? That sometimes indicates that there is a broken gear tooth inside the actuator. Are we talking about a little air or a lot of air? Sometimes junk does get into the air box and will stop the door from repositioning correctly. You can try that. Yes, the blending door is directly connected to the actuator.

1995 GMC pickup. Cold AC will blow through all settings (defrost, front vents and flloor) but warm air will not come out the defrost. You can hear something click in the dash that you assume is some kind...

good work, the clicking noise you hear is the blend door trying to move. this door is what controls the temp. the most common reason is the actuator motor is bad but sometimes the door hinge breaks, this hinge slides into actuator and is used to move the door. you will need to locate it on the heater box by locating the noise and then remove the actuator and see if the hinge is broken, i will try to enclose some picture to help you. good day, hope this helps.johnjohn2_142.jpgjohnjohn2_160.gif

I have a 1995 GMC Sierra K2500 pickup and i need to know where to find the blower motor and replace it. it will not blow out any heat right now.

I think i may have an answer for ya...Is your truck blowing air at all? if so its not within the blower...the problem is actually the a/c actuator. a little bit cheaper and easier to install...had the same problem with my truck...replaced everything but the actuator which cost a crapload of money and found out it was the actuator. your truck may require an upper and lower so check with local auto parts store...average price run about 60.00 for each.
