[KYCOL]

Hey Guys....

I'm new here, so bear with me...

Just bought a really-really NICE 1983 300D Diesel 5 cyl ...AND

I've got some problems, then after checking parts and catalogs, I think, Ive had a stroke!!! $$$$$$?????....LOL

It runs GREAT, gets great milage, looks great inside and out, just serviced it today.. now, heres my problem:

A. No heater/Blower.. apparently..not working.

B. No Air Conditioning...

C. Climate Control Unit appears not working...

HELP!

Also for "Those that Know" give me a brief evaluation of this year/model ( reliability?) etc...
