The ears on the frame for our dash A/C control unit have broken off. We've looked through AC Delco and Motorcraft catalogues, called every Ford and Dodge dealer in our area, gotten on the internet, etc., etc.,and we cannot find anyone who can help. The chassis is John Deere and the engine is a 460 Ford. Anyone got any ideas?

Many motorhomes have aftermarket a/c units, not units from the engine mfr. Check whatever documentation you have, to see if it holds a clue as to what you have.

Check for any mfrs. plates that might tell you as well, and check to see who mfrd. your compressor.

Try an internet search for aftermarket automotive air conditioners, too.

Give Freightliner a call in NC. Have your frame # year, etc. they are very helpfull.
