The heater on my 1998 Yukon does not work unless I rev the engine up or I drive it. When I come to a stop light it will quit blowing hot air.


Sounds like the cooling system is low and has air pockets. The rear system problem could be something electrical.

I Have a 2003 Yukon denali & I dont get no heat i change the thermostat & antifreeze but no heat


1) Check your water pump is working OK and
2) You may have an airlock in the system. Take the expansion or header tank cap off, set your heater control for hot and exterior air. Start the car and run it till warm. With luck you'll run any air locks out of the system. While warming up, and being very, very careful, try squeezing the main radiator in and out tubes (The fattest) this may also move any air locks on. BUT BE CAREFUL, STAY AWAY FROM AND FANS AND PULLEYS. IF NOT SURE, DON'T DO IT OR STOP THE ENGINE FIRST.

With luck, you should soon start to feel warm air coming from the vents.

you need to check the blend door motor. it may be getting stuck halfway so its letting the cold air mix with the hot air thus making it not as hot. Its a common problem on these GMC trucks and SUVS.

I need to know where is the #1 spark plug on a 1998 gmc yukon


V8 engine? That would be drivers side front. Remember that TDC is number one piston up (On the compression stroke, not exhaust stroke), timing marks at zero.

On my wifes 2004 yukon, the engine warms up and the blower works fine, but it takes forever for the air to finally blow warmly. when it finally does, if we switch it to another location (floor or defrost),...


iwould check the selector motor,and also replace the thermostant,start with the stant first,the selector motor is what runs the door for hot or cold the motor is a common problem,if the temp gauge is showing a quick warm up temp then its the selector motor, if it takes a while to reach operating temp then replace the t-stant,also make sure the coolant is full in radiator,check when cold or warm,dont open when hot, hope this is helpful.
