Heater blower resistor is what controls the low medium high speeds...
It appears your blower motor is not working correctly on your 1980 Cadillac Coupe Deville. The vents are for both AC and heat. You may also be losing vacuum pressure. If you cannot find the source, your mechanic can help you do so.
it's best to get a new blower and replace it. you have to access it from under the hood about half way across the firewall there will be an access panel that has to be reomved. it takes about 2 hrs. if you are mechanically inclined go for it.
