Hi tiresmoke,

Thank you for the donation.

The blower motor receives its power from the blower motor relay in underdash fuse box. There is a possibility the relay is faulty and sticking causing it not to cut off when power is disconnected via the ignition switch. Try swapping the relay to see if it works.

Your welcome. But I found the problem out yesterday 1-9-10 surfing the net. Because I didn't feel like waiting for a tech to answer back. Which im glad I didn't because that's not what the problem was. The problem is. When I read in another website. Is under the hood there"s an accessory relay or coolant relay on top of the right side of the radiator corner. Which there's two of them which I replaced it which cost for each one $32.00 and that was the answer to my problem. The fan shuts off and the inside power is cut off the the ac/heat. So for any one else who has this problem as I did. Don't put all your eggs in one basket waiting for an answer. Do alot of research first which is free. Thank you anyways

Thank you for the input.

You are correct, the relay tends to short out when water gets to it, especially if the relay has detached themselves from the mount and becomes inverted. Water would collect and penetrate into the relay and cause it to short resulting in fans and blower to work.
