Well if it was up to me a cameo on the show. But since it's not, nothing.

Guess you'll have to settle for another challenge. The next one will be a little harder.

No offense, but maybe the next one should be a little easier. I'm guessing that most of our members, if they decided to try a repair, would grab a can of refrigerant and top off the system (remembering that a lot of us, especially the members going back to the "Shadetree Mechanic" days have their roots in our own garage 'turning wrenches'.

But certainly nothing wrong with a cerebral challenge; just saying though.

No offense at all. I have a lot of these to choose from. Some are quite easy, and some are absolute nightmares. Maybe an easier one would get some more active participants.

Many would start by trying to "top a system off". Sometimes they fix the problem as this one would have, and sometimes they add a problem on top the original issue by overcharging the system.

I looked at the superheat charts early in the (mis)adventure. For that ambient temp, the low and high pressures at idle were in the range. Seems the only way so tell is to have manifold guages long enough to run into the passenger compartment while driving or have some giant fans in front of the car.

Actually this one has quite a bit of learning value. It made my head hurt a bit to start, but the answer at the end was worth it.

One, I had no idea auto manufactures were using variable compressors.

What manufactures are installing these and around what year did they start?

Two, I never worked with a variable compressor and had no idea how it controlled or acted, especially when charge was low.

If I own one in the future, this will be handy to know.
