if the a/c belt isnt put on will the heater still work? the logicon or whatever its called turns on but it doesnt work. like if i pick to defrost the windshield it flows out the front the whole time. is their something that i can pull to make it stay on windshield cause i dont use it anyway. how can i get the heater to work?

Well, only thing I know for sure is that the heater WILL work without the AC belt on. Why do I "know" this? Because it is cold as shi* here in Kansas right now, and I stay warm. I cut off my AC belt last summer when my compressor froze up. Still haven't reinstalled the new one, so I still don't have a belt on it.

Hey i'm having the same problem. the logicon will light up the different locations to flow the air, but it always flows out the front, and the defrost never comes on, which i badly need. the air is always cool too, never hot or even warm when i move the temp control. when i move the control from cold to warm i don't hear any mix motor... how can i fix this problem? do i need to take the whole dash off? I really don't wanna do that and if i took my car to the dealer or some kind of specialty shop, anyone know how much they might charge and also how much labor(hours) will be needed to complete the job?

ok here is what you do look under the driver side dash you will see some levers one off them is the one you can disconect the plastic piece from the motor and do it manualy I have no intesion of ever fixing my logicon I get by just fine bying in control.

cool thanks, what will this lever look like? this won't solve my problem about not being able to turn on the defroster tho right? but at least now i can manually make it always blowing warm air right?
