Operation on traffic, really? Why would this be in the service manual and not the owners manual?
I never had a air conditioned Mopar in the day, and wouldn't have expected cooling issues on a new car with A/C. I just find it interesting. I have been trying to sort out the A/C on my 67 Coronet, and the system is sealed and now charged. All three actuators are functional and have vacuum to the switch, but when I push the max A/C button one of the actuators blows two the hoses off. It's either a bad vacuum switch, or the wrong vacuum switch or the hoses hooked up wrong, but in reading, I found it unusual.
