My blower motor continuesly runs with ignition switch turned off

Fairly common problem for GM .. The blower motor resistor is the culprit!.. There are a couple different types depending on the climate control system.. NAPA should have the repair kit.... However check with dealer first. .. Need VIN befor calling...... Oh BTW, it's really not important but the relay is an integral part of this resistor, just so everyone knows! (*Handy* diy'er = YES!!)
