Learned a few new things from my mechanic tonight which you all may be interested to know -

- The AC will always blow colder on the passenger side. ALWAYS. This is normal for most GM cars.

- If you close the vents on the passenger side thinking you will get colder air on the driver's side, you will get warmer air instead. For some reason, the AC will blow a few degrees colder with all the vents open.

- The AC system, like all the other parts of the car, doesn't like to sit. You need to use the defroster at least once per month during the winter, otherwise the compressor seal won't stay lubricated and can start to leak freon.

I'm hoping this last is what happened to me. I've used my defroster once in 3 years. shocked

I've got a full charge now and blowing COLD. Sweet, sweet, cold refrigerated air!

Good tips. I forgot, does the defroster turn on automatically in winter if you set the AC to auto? I thought it did, but not sure.

I always try to kick the heater on once in a while in the summer months, and vice versa for the a/c in the winter. I read somewhere that not using them for months on end could cause problems when they are engaged months later.

dont remember where I read it though. Pretty cheap insurance to hit a button once per week if you ask me.

You got me. I've only needed it the one time.

changing supercharger oil should the engine be warm or cold in order to draw the oil out?
