A/C troubleshooting help Sought...

A/C troubleshooting help Sought...

Summer is almost over, but I still need to figure out what went wrong with the A/C while the Defender was in storage for three years. It does not appear that the A/C system is engaging the compressor's clutch, as I don't see it spin when the A/C is turned on. I don't see any obviously disconnected harnesses, and I tried 'reseating' the plugs and connectors I could see. Any thoughts? Do the clutches go bad frequently, or is it more likely electrical (in a Land Rover, who would think?!?)?

Interior fan works fine, except it blows alot of hot air...

Have you checked the pressure in the system? Its very common to lose refrigerant when a car is stored that long. If the pressure is low, the trinary switch will prevent the compressor from engaging.

Yeah, the trinary gear . . . that's what I was going to say

x2. if your pressure is fine, I would suspect electrical. I've never heard of an A/C compressor clutch go bad. They're pretty reliable.
