The a/c is working pretty well now. It seems like it still has a tendency to freeze up, like it did when I bought the truck (with 25k on the odometer). I think below dash add-on units are more prone to do this, though.
Ask him to explain any modifications that were made to get the part to fit, as I seem to recall it may not have been a straight fit, exactly. The parts for this unit, though, are simply not available, or extremely cost prohibitive. Neither my mechanic, nor myself could find anyone carrying an expansion valve, or showing it listed to readily order.
Other part substitutes can be made, like the condensor. If the total cost on repair gets too high, RDS and Rovers North offer replacements. I'd rather put $2k in a new unit then spend the same over a two year period on various odds and ends, even if I had to save for it over a year. By the way, Jeff's number is 225-343-7525.
