94 blazer heater controls electric or?

[Kain]

i have a friend here in town that bought a 1994 blazer and the defroster is out
are they electric or cable like my 82? Told them i would help them, just wondering how much trouble it is.

electric or at least my 94 suburban is. On either side of the transmission hump on the sides of the ducting there are a total of 3 servos. 2 for the blend doors and one for the temp control. Dorman carries replacement servos.

The driver side is the mode door iirc.
