My heater has never worked. So I removed the 2 rubber hoses in the engine bay where they meet the fire wall. I shoved a hose over one hole, and turned it on. I saw coolant come out of the other hole, so I guessed that the heater core is not clogged. Any time I turn my heater on, I never can detect moisture on the floor, so I think that it's not leaking. (I did detect some water, but I think it's from me blasting the hose there, it didn't smell like coolant and was very cold).



So what's the deal? The air doesn't even get warm. All I want is some defrost, and maybe a little warmth for me fingers.

maybe the logicon is messed up

with the key on engine off, when you move the heat lever do you hear the motor?

Baldy 12-15-2004 05:34 PM

Yep, I can hear the blower motor if that's what you mean, at all different speeds. I can also hear the sounds of the little motors when I switch from face/feet/defrost and such. All the indicator lights work fine as well.



I also felt around under the dash for warm air in case the ducting was blowing it somewhere else.

its gotta be the logicon, its just not switching to get the air through the core

when was the last time you changed the thermostat?

change that and see what happens, open thermostat will not allow heat

Yeah open thermostat = engine runs too cold = not optimum for motor = no heat for you in the cab.
