I'm having some weird problems with my A/C that I've shared before, stuff like air on passenger side is 10 deg warmer even when both controls are on max cool, and also if the heat turns on when car is started, it will not switch to A/C until the car is turned off and restarted.

Some asked if I was getting error codes, which I didn't think I was. But now as I've been paying closer attention, I've noticed that every once an awhile (about 1 out of 10 times) the recirc and ac light will blink when the car is turned on. If I turn the car back off and then on, the lights don't blink again. And again, it doesn't happen every time I get in the car, just every once and a while.

I've got a replacement control unit on order, so hopefully it might solve some of my problems, but if anyone familiar with the error codes, and what might cause them to be intermittent?

Thanks in advance!
