Heater wont come on
 

i tryed unhooking the blend door cable and switching it manually, it didnt change anything. iv been told it could be my cam not making enough vacuum but idk. coolant has always been nice and clean so i dont think the core is clogged but i could be wrong. a/c works but when i switch it to heat it just kinda gets room temerature

The fact that you switched it maually proves that it is not the cam. Or you moved the wrong door. I beleave that there is one on the top behind the glove box.

how many are there? i moved the on on the bottom in front of the center console. is there a difference with LT1 and LS1 a/c systems?

anyone?

also depends on the temp of your coolant ? my car runs about 180-190ish and the air never gets too warm (unless i sit in traffic).

well i have a 160 in it but i had it last winter too and it was atleast intermittent then

actually. even with it on ful heat and defrost the a/c still kicks on. any ideas now?

I don't know why, but the A/C compressor is supposed to kick on with every setting but Full Defrost (and I could be wrong about that setting also, might kick on for it too).

This is per the driver's manual for my '01.
