the car now has 167K miles on it.
It has been an excellent upgrade for me.
But now some things are starting to happen.

1. when we have wet weather all of a sudden now I have water coming in from the firewall foot area on the passenger side of the car. Not sure what is causing this to happen?

2. Passenger side door mirror assembly unit. The mirror and heat work, but when I put the blinker on the raking a right turn the light in this assembly does not blink. I checked the bulb out and it works as I tested it on the driver side. What is happening here?

3. Now that we are into the springtime heading into summer time a/c would be nice.
This control system has always been set to automatic control. I noticed that the cars exterior fan comes on almost immediately after I start the car up. At the same time I also noticed that I have no Cool Air for A/C now. What do I need to do here?

4. Also noticed that the headlight washer system has never worked on the car either. What should I be looking at?

I look forward to the replies. Thanks
