i have a 98 chevy silverado and my heater is stuck on high. anyone know what it could possibly be? thanks guys.

 

Be more specific about ....stuck on high.

 

what else can i say? the heater is stuck on high.

 

ok so when you look under the hood there should be 2 hoses going from your engine to the firewal on the passenger side fo the truck, when you move the temp. control there should be a valve type thing on the hose or block move to open the hose to accept coolent, that might be stuck.

 

Do you mean the fan is stuck on high or the temp is stuck on high.(hot)

 

the temp on high.

nice tahoe in the pic btw
