When I turn on my A/C fan for A/C or heat, I heard a clicking noise by the blower in the moment I turn it on. It turn off and come back again. the light on the control bottom get off and I heard the clicking noise at the blower motor like 2 or 3 times so I turn it off and then turn on back again and stay working good.
Relay faulty?

it wouldnt be your fuse it is probably the risistor for the blower which is right beside the blower

the blower motor is like round cage and the only way to get to it is to take appart the dash. not the insterment cluster but the top and through the glove box is probably the only access. i doubt you will find a schematic just take lots of pictures while taking appart of what each screw looks like as it comes out. most the heater vents are in your way taking them out is not only screws but plastic barbs. just take every thing appart that is plastic and keep track of where it goes the cage you want is dead center of the dash. you dont need to take it out just get access to it. also what ever got there probably fell from one of the vents that blows onto the windshield so the top of dash removal may be easier if all you need is access to pull out some trash.

Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

you have something stuck in the squirrel cage of the blower motor.All you need to do is drop the glove box open and look where the cabin air filter is,remove the cabin air filter and reach down there and pull the stuff out;its usually a leaf or napkin.
Yes both relay and switch are possible.Needs to be inspected. http://schematicsdiagram.blogspot.com/2011/12/blower-motor-resistor-shorting-problem.html How to remove Blower
