So how is your ride holding out with this rain? Are the door speakers dry?, How about the seats, are they dry or do they seem damp?
Did you know your air Conditioner is a great de-humidifier? (yes you can use it in heater mode)
Seen any spills because of the rain? Hopefully bo one got hurt?

We just saw rain for the first time in a while. It was a tropical -2 today which is pretty nice, i almost wore shorts and a tshirt. All my crap is dry. as for the AC being a great de-humidifier, never put much thought into it. And haven't seen anyone crash in the rain yet, although i'm sure they will. People gotta learn how to drive.

This is what I have always been taught anyway...

Nope. The reason the AC light comes on is the AC system helps out the defroster.
The incoming air hits the AC evaporator which actually cools the incoming air even more and condenses the water out of it. Then the air hits your heating coil and is now heated up and enters the car with very low humidity.
The warm air then picks up the humidity in the car and on the inside of the windows and helps to defrosts them.
This is similar to why we need humidifiers in our houses in the winter. Low water content cold air enters your house, gets heated up, and the warmer air needs more water content so your house dries out.
Take two identical cars, one with AC and one without. Run the defog on both and the AC car will clear first.

That would be why I had to unhook my a/c unit in my car awhile ago. It started to spark and the a/c hadn't worked for years but was never disconnected and one day it started smoking and sparking when I turned the car on (defrost was on). Makes sense to me. There was no freeon (whatever its called) in the a/c unit because a) dosent work and b) i dont use it) in the ac unit so it was useless.
(It dried out or whatever but the belt was what was smoking and sparking)

Sorry, what I meant to say is "what Eli and Aaron said".
Yes, it lowers the humidity of the defrost air and the concept works well. But it also runs the compressor which needs to run occasionally to keep it operational.
I had a T-Bird that dropped idle every time the A/C came on in defrost, so three years into owning the car I disconnected the A/C compressor in the fall to stop the idle drop during winter. Guess what - in the spring it wouldn't even spin up and nearly burned a belt.
It does both.

Aside from the defrosting feature of the A/C , I can't see the point in having one installed in the new car I'll get..,someday.
It's a nice convenience, and even law in some places, but for the month and a half it may be needed in Canada, for me it's just not worth the expense overall.
