I am trying to figure out if my original Armstrong A/C is still good or not in my 1965
Ambassador.. Looks brand new from inside trailer but does have cracks in outside cover and does allow water to leak into the trailer I have it covered by a tarp to keep the rain out. I am told that whatever I do I should repair it unless the compressor is bad. It doesn't run as far as I can tell so I'm not sure if it is a keeper??? Anyone have advice on what I should be doing to diagnose???? Doesn't turn on.......maybe the wall thermostat doesn't work anymore?? Just guessing. thanks.
