A/C blower wont shut off

My blower moter wont shut off and runs the battery down. Anyone have any sugestions

stuck blower rely? try swapping it out.

do you know where the relay is located?

On my 93, the FSM shows a bank of four relays.  Two are for the blower. One Hi speed and the other Low speed.  I believe they are in the engine compartment, passenger side near the evaporator housing.  If you can't find them, let me know and I can try to post a diagram later tonight or tomorrow.  Good luck

Is your ac electronic or manual?

mine had a similar episode a while back. I pulled the fuse to save the battery, poked around a t a few things, got stumped. The shop fixed it, replaced a circuit board. No probs since.
