93 TC newbie with questions, what more could you ask for

I purchased a 93 Town Car and love it to death.. I just hope it's death is a long ways off. My questions are....
I have the keypad on the door, does this mean I also have remote keyless entry?

My air conditioner control buttons have been used too much being it is Arizona and I can't see what they read....only the white light shows. Where can I get a replacement for this automatic climate control for my dash.

What should I be looking for to prevent major troubles down the road? You know, a little PM on the car before it goes from Lincoln to F.O.R.D (fix or repair daily)

Thanks for the help from you friendly computer nerd here in AZ. :uhoh:
