This should be the W123 model.
Looks like this model had both electric windows and handles. If electric, the first thing I would replace is the switch:

Either there's a a leak in the vacuum line, or the switch needs to be replaced. Most likely ? The electrical switch on the center console. Twenty minute fix.
