I am in Costa Rica and have a problem with my 1994 Cadillac Fleetwood. There is no authorized Cadillac mechanic in the country and I have to rely on local mechanics.

The problem is that the blower fan is on at all times, even when the ignition is off. The only way to turn off the fan is pull the fuse.

My mechanic has searched all over for the faulty relay, which is what we think is the cause of the problem, but it is nowhere to be visibly found.

Is the relay the problem? If so, where is it located. And if not, what could be cause of the problem?

Especially the info on the second page.

Thank you for your reply. I had assumed that, what I cant find is where the part is located.
