1985 Mercedes Benz 190E, No air cool or hot, just quit!

This could be a couple different things. You would need to remove dash to inspect and test these however. First, your vehicle has a blend door which is what mixes hot and cool air together to adjust it to your climate control settings. Your vehicle also have vents which open/close to divert airflow to different locations. If your vehicle also has a setting for fresh/recirculated air 1 or more of these things may not be working properly. It sounds as if your getting warm air radiating inside your passenger compartment because your vents are not closed when your ac/heat is off

check fuel injectors for dirty , fuel filter

It is a problem with the fuel pump relay behind the battery firewall. Replace this then you will be OK.

first the a/c issue is probably due to low charge. Need to recharge, if you still had R12 in there you need to have it updated to R134A or find someone who has R12 which is tough.
Starting issues are tough to explain without more info but if you mean your starter doesnt turn the motor I would suggest a new battery as you probably have a weak one or it has a bad cell. If your starter turns but it wont start could be the OVP relay, the cold start vale or any number of ignition parts from the coil to the plugs.
