Huh! I can't seem to find any controls for windows or A/C on my motorcycle. LOL
Seriously, just returned from another 2,200-mile road trip. Had to use A/C both for safety as well as comfort, but not all the time. In a 4.7L Tundra towing a trailer at 55 mph I found the A/C cost was negligible.
I missed seeing "solar effect" mentioned earlier but that puts a big bias on the ambient temp even when the sky is not completely clear. For my 1.8L Spectra hatchback I made a solar shade from foil laminated foam insulation. It only had to cover the top 1/3-rd of the rear glass to shade the seat. Previously our boxer panted even with A/C on high. Afterward we found the A/C required less often. (Errata: descending Mt. Washington (NH) in 1st gear (manual) I found the A/C button an effective compliment to engine braking.
Any recommendations for an aftermarket kit to cycle the A/C compressor? Either t-stat or duty-cycle based types would interest me. Personal experience would be particularly appreciated. If not, I can make my own but a quality kit might look nicer.
Cheers
