You may need to replace or rebuild your mode switch. It would cause the heater/A/C to not function properly and would also cause a hissing noise. A vacuum hose could have also just come loose. If the mode switch is stiff to turn then it needs to be rebuilt anyway and while you are at it you can check all the hoses. To set the clock there are 2 small holes on either side of front panel of the radio. You stick a toothpick (or similar) in to set the clock. The one on the left is hours and the one on the right is minutes. Don't push too hard. The venders sell a new diaphram in a rebuild kit if you need it. Mostly the mode switches just need to be taken apart, cleaned, lubed with silicone, and reassembled. Next time search the archives, I don't think Google is going to help you much with the technical. You can also go to dmcnews.com for technical help.
