Moss AC Kit

I have mine working nicely now. I have aske Moss for a wiring diagram so I can trouble shoot it if needed. I also am adding a temp control for inside air. Its cold and just has fan speed control.

That's interesting, about the need for a temp control.

Pictures!!!!!

i think a lot of people will want to know just how well does this thing work during the summer heat & humidity.

I've owned other convertibles with A/C - none in the B yet - and it does help. Top up, the cabin is cool and the humidity is low. Top down, humidity is obviously unaffected but you do end up with cold air blowing on you so the comfort level is better than without.

You're going to find that an AC in a roadster struggles to lower the cabin temperature during the heat of the summer. The problem is that there is too much hot air infiltration (and other heat loads) in the cabin for the AC system to efficiently remove the heat.

An AC system works by removing heat from a confined space. Our soft tops do a very poor job of sealing the interior of the car, so in really hot temperatures, the AC air intake (the evaporator) never starts pulling in progressively cooler air as it should. You can help the situation by sealing and insulating the firewall at the engine compartment and insulating the floor pans and transmission tunnel. Tinting the windows also helps according to the vintage AC dealers. This helps with the "other heat loads." But the biggets factor in my opinion is hot air infiltration, in my car I notice the opening where the top snaps down just rear of the doors, and of course the loose fit around the windows in general.

I should have my hard top ready for AC testing in a month or so. I'm hoping that a better sealed interior will help the AC system actually lower the interior temperature on those 100 degree days, instead of just blowing cold air on my face and legs (which is better than nothing).

I would assume a GT AC system would work well.

Sofar Moss hasnt responded.

Gil, I'd be willing to bet that if you check out Vintage Air you can find a wiring diagram that pretty much matches what you got from Moss. You already know the bits that you've installed, so that should be self-explanatory. As a bonus, you will get the wiring diagram for the temp control.

thanks i will look at vintage air.

Guess waitin on Moss is slow
