NO HEAT OR A.C.

1998 Dodge Dakota • V8 4WD Manual • 150,000 miles

My Dodge Dakota has no heat and when I use the air conditioning in the summer, it puts off fumes in the truck. When I shut the truck off the coolant system gurgles. Any ideas would be appreciated.

The fumes and the gurgling will be too separate issues. When you say no heat, I need to know if the blower comes on or not. The fumes would be either (depending on what it smells like) an a/c line leak, a coolant leak in the heater core or mold/mildew.

As for the gurgling, that will either be because the cooling system isn't building up enough pressure due to a failed radiator cap or a leak in the system (again, possible leak in heater core), a blown head gasket or the radiator fans aren't coming on/shutting off too early after engine shut down. (Due to faulty ECT sensor)
