My 95 Maxima is not blowing any heat into the passenger compartment.
I''ve flushed the cooling system, and ran a hose from the intake line
of the heater core so that the water ran out the disconnected hose, so
I'm pretty confident there's no blockage. This was all done wihtthe
t-stat removed as well so that I got complete flow through the engine.
At idle when the car is warm, I get about 102F on the surface of the
hoses going into and out of the heater core. The air however coming
into the passenger compartment is still cool. When I move the
temperature slider from cold to hot, I can feel that there is an extra
load on the blower and the flow is decreased through the vents. I get a
little feeling of warm air, and then it goes cool again.
Is there something else that coud be blocking the air from going over
the heater core? I've also read about a vacuum connection - what is
Any suggestions woudl be greatly appreciated.
