The blower speed controller is located under the hood on the right or passenger side on the heater housing just to the side of the heater hoses near the very back of the right cylinder head.
Yes that would cause the concern you are having.

i had this problem on my 2004 and it was the headlight module when it gets hot it turns out, and comes back on when it cools off

that is caused by a "circuit breaker" not a relay. when it starts flashing, carefully go over the harness from the firewall to the rf headlamp, there is a short somewhere.

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.
