Question about 1994 Nissan Pickup

1 Answer

1994 nissan pickup--heater not blowing hot enough air

Heater does not seem to blow real hot air, nor does it blow real cold air in the summer when AC is on. I just changed the thermostat, so hot air is now about 15 degrees warmer, but it still won't dirve me out of the cab like it used to. Also fan seems to have a funny sound like something is stuck in the fan--leaves or something. How do I get inside system to check for foreign object obstrucing air flow and fan action?

Your fan motor is shot, motor has bad brushes replace it, if u feel its still not hot, drain your rad and but a 28 oz bottle of pine sole and add water till full, run it for about 20 mins. drain, run strait water, drain, then put anti frezz in with water, 50/50 mix or mix your own. it should clean your cooling system compleatly out.. do not turn heat on while pine sole is running throw it, gives of a bad smell.

Heater blows only cold air. in and out hose are both hot, what could it be.


The door that mixes hot and cold air seems stuck in the cold air position. Check for a vacuum hose leak.

What's your problem?I have a 1996 Chevrolet Suburban. The AC is blowing out hot air. I have had the truck for 6 years, every Summer its the same thing. The ac does not get cold, I take it to the m


To clarify - - if the truck has rear and heat, you have two heater cores and two evaporator cores. The evap cores carry the freon.
If the leak is in the evap core in the front, the price is probably right.
