92 s-10 4x4 the heat doesnt work ive changed everything therm water pump -heater core any one got any ideas all the vacuum is working prop.?
if your bypass line is blocked it will not send hot water through your core With the engine warmed up and running, feel both heater hoses with your hands, if both feel equally hot the temperature blend door actuator is broken. The entire dash assembly must be removed to gain access to the temp blend door actuator.
Why is the heat not working on your 5.3L 1999 silverrado Pickup 4x4?
Sounds like your blend door may be broken. the blend door opens and closes on the heater core to allow heat into the cab by letting the air blow over the heater core. The heater core basically looks like a small radiator and when the blend door gets opened up, it allows to air from the blower motor to blow through the heater core fins and that heats the air before it is pushed out the vents into the cab... Check out www.heatertreater.net Those guys have videos on there of what I am talking about. It may not be your blend door though. Could also be the blend door motor or the dial to turn from cold to hot... I would check that blend door first though...

It does not have one. It has a 4x4 Actuator in the front housing.
Why would a 1999 GMC Jimmy 4x4 not engage?
It could either be a problem with your 4x4 switch in the cab, the actuator that connects the front right axle shaft to the drivetrain, or the transfer case itself not sending power to the front driveshaft.
Your 4x4 on your 89 Chevy silverado will not work?
Need to check the front4x4 actuator on the front housing to see if its working. there is a switch on the top of the transfur case that sends power to the front actuator to ingage 4x4
The 4x4 is engaged but does not engage into 4 Hi on your 2000 Silverado Z71 4x4?
It sounds like you need a new actuator. there is two things that lock in when you use 4x4. one is the transfer case and the other is the front diff. the front diff is turned on by an actuator. if you have a problem with the actuator the front axles wont lock in. even though the transfer case is engaged.
Your drive shaft is spinning but the wheel on your Chevy 4x4 wont turn when 4x4 is engaged?
If it has lock out hubs, Then you have a bad lock out on one side are the other. If it does not, Then the Actuator on the front housing is not ingaugeing. Need to check that with a test light. If it has power going to it , Then replace 4x4 Actuator. If no power then check 4x4 fuse in fuse box.
