Hi
I've got a 5.9 1996 2wd lariat. I recently replaced water pump belts etc...
My heater just stopped blowing hot. the truck will warm up and start blowing a little warm but the more you drive it turns cool.
Both heater hoses are hot
blowers work fine
temp sits at 198 once warm
a/c works fine
My question does this sound like a clogged heater core or blend door. Also how do I check to see if blend door is functioning properly? also I do get some gurgling in the dash from heater core (what is the cause)?
thanks
