Yes, the sample blower that pulls air through the small grille near the rear view mirror. The blower was in a number of different locations during the 124 production run.

To check it, cut a 1 centimeter square piece of paper and hold it to the little grille with the key on. If the paper stays in place the sample blower is working. If not, find the blower, check it for voltage and if it has voltage and not running, replace it.
