Ok, I removed most of my a/c components, and I figured I should fix my heater for winter, and for defrosting.



When I turn it on, full heat, full fan, I feel no heat, and the fan blows not very much air. I pulled the blower out awhile ago, just to make sure there wasn't any crap/dead animals in there, but that's all I did. I don't see any evidence of coolant leaking when the heater is on. Someone suggested to me that my thermostat might be stuck open, but my car's temps seem to heat up in a reasonable time, so that makes me think the thermostat is fine. Also, all the fan settings yeild different airflow, and all the airflow switches (dash, feet, defrost...) change without fault.



Where should I start?



Also, if anyone else has heater problems, and since winter's approaching, please feel free to post in this thread. Consolidation is good.

 

if you have the key on engine off, and you play with the heater ***** do you hear motors and relays?

I'll check that out tonight, thanks for the tip.



Whether I do or do not hear them, is there anything else I should/can do before tomorrow?

 

you should hear em btw, if you dont hear em you have a logicon/heater motor issue, if you do hear em its something like a plugged heater core

ok, sounds reasonable. If it's plugged, can it just be flushed out with pressure, or should it just be replaced?

 

flush

 

i would also change the thermostat with a factory one, if you never changed it and dont know the last time it was changed its a good idea anyhow

 

yeah stay away from stant and all that, nothin but the best for the rotary in your life

 

its like $10-$12 from the dealer anyhow, with a handy dandy self stick gasket

 

my old T2 the logicon was shot. i had to crank it to heat manually
