96 marguis

my 96 marguis only blows heat.its full of freone ,no leaks and compressor still works..whats the problem??

Check the blend door motor. Sounds like that might be your problem. Get in car, close door, turn key "on", wait for any warnings to stop, listen for a small motor noise while moving the heat control lever from cold to hot.

My 96gm does the same thing intermittenly. I found when the weathers cool the blend door motor hums open/close, but won't work when the weathers warmer.Did you have any luck with yours I was thinking it might have something to do with in cabin temp sensor.
