If the engine is running at proper temp you are looking at a few possibilities.......heater core plugged if you have used any sort of stop leak that can sometimes plug them.....at operating temp carefully check if both heater hoses feel as if they are the same temp(they will be about 1 inch thick,much smaller than the radiator hoses and will pass through the fire wall on the passenger side of the fire wall),If one is noticeably hotter\cooler you probably have a plugged heater core...................................................,maybe the system that changes hot to cold is not working...not sure which your voyager has but there are several ways the car manufacturers do this.....a cable,vacuum switch with vacuum lines,and an electric motor.There is a door in the heater box (behind your dash on passenger side..........not visible from the outside of the heater box though) and when the selector on the dash is on hot the door is in one setting And on cold another.I would start by removing the heater controls from the dash and check to see that the cable\wires\vacuum lines are in tact and go from there. A inexpensive repair manual can be obtained from your local parts store.most give detailed instructions and pics to guide you in repairing almost every part of your vehicle(i recommend the Haynes line of manuals)
hope this helps.......Good luck!

You most likely have a stuck air temp blend door. In order to repair this check the actuator 1st, then is it is ok u will need to pull the dash to repair the door.

My 2000 jimmy has heat problems. the heat goes from cold to hot to warm to cold etc. what could the problem be?


If the temp gauge is now more stable, the problem is in your heater system, not the engine cooling system.

It probably low on coolant. The heater will blow cold when there is not enough water (coolant) to keep the heater core full. Check the radiator (not the overflow reservoir) when it's cool.

Temp gauge goes from normal to cold so does heat

Heat blows cold air front and rear when sitting still or @ low mph.


Usually a sign of low coolant or a blockage in the circulation.

Heat goes in and out and the temp gauge goes up and down


Your temp sensor has nothing to do with your heater. The temp sensor needs coolant in order to work properly. So first check the coolant level because if it is low your heater will act the way you describe. Once the coolant gets low enough the heater will blow cold. Another possibility is the radiator cap. After the engine has warmed up it expands when it cools down it contracts. As it is contracting if the cap is weak air can be drawn into the system and cause air pockets to form and will cause the same problem
