Gilly-Roger that.

Well, I've been doing some research with everyone, and I've pm'd with blackmercedes and he is now telling me of the underlying problem of leaking refrigerant and my fix will only be a temporary "band-aid".

AMOF today, back at work I was chatting about my situation with an HVAC troop and basically he told me that I need to recharge the freon, because it leaked out somewhere. I imagine it is normal to lose your refrigerant eventually and as it won't last forever...right...and she is a 98 C230. Standard maintenance you could say.

I think I am convincing myself here and/or need reassurance that I should proceed as planned per link from Dan

and hopefully there is not the underlying problem of a leak to be remedied.
