Not getting any heat out of the heater but both inlet and outlet hoses to the heater are hot. Still can not get any heat through the vents. Get alittle warm air when in the defroast position. Themostat and water pump have been changed. Any ideas?
Thanks for your help.

 

does the fan blow any air at all? or just cold air?

 

do you have manual a/c or elec contol?

 

Look for a hot water valve that may be stuck closed. It is located on the heater hose from intake. It may be stuck closed. I suggest replacing it. 8 to 10 dollars is a reasonable price.

 

Hey I have a 1992 and had the same problem ended up replacing the heater modulater 800.00 later, you have to take the intire dash loose and replace the thing. Good luck[img]smileys/smiley5.gif[/img]
