Default ac heater unit

I just bought a 89 and fixed the engine and now to the other stuff. The heater unit is doing some funky stuff. Once in awhile it is fine and then all the light light up the temp indicator flashes all wierd. Is this the unit itself or could it be something simple

The security light is supposed to flash...just not all the time.

No "factory" remote entry for '89.

use the torx bit....."lefty loosey righty tighty". Here's what I do:

Targa removal:
Slightly loosen all 4 bolts that hold the targa. Back out the "rear" torx bolts until they spin "free" then do the same for the "fronts". Remove the top.
Targa install:
Set the top in place. Start both the rear bolts then tighten both until the are about 1 full turn from tight. Start both bolts then tighten the front bolts until they tight. Go back and finish tightening the rear hardware.

Ok I fixed it for the most part the only thing is it only goes up in heat. It will not let me decrees the temp. Did I miss a conection or is the unit done?
