I don't know if I've ever heard what the Comptech S/C sounds like in motion, now that I think about it. Which seems wrong, given how many cars I've seen that had one. I have never used the auto CC function with any regularity in my 6GA. Unless it's extremely hot or extremely cold, my windows are down and I'm lettin in whatever's outside. Right now the blend door actuator is broken, so I can manual switch the car to hot or cold, but the actual CC dials are useless haha. Time to switch it over to heat for winter...or you know, replace it. I still have an auto CL-S cluster sitting, always liked the way they look. I modded my 6GA cluster since I never did the CL-S one. Nice CL-S wheel, that was always one of the best cheap and easy mods for the 6GA.
