Sunroof intermittently works
 

I have an issue with the sunroof that I did not see searching the forum. I jsut acquired a 98 Civic DX with power sunroof. He told he it had intermittent problems. When I looked at the car and evaluted it, it worked fine. The next time, I hear the button making a clicking noise (also electric sound as if its trying to work near the switch- the motor?). The next day it would work fine, noisy but fine. I took the switch out and the contacts are clean, re installed it and the same thing, not working. I am considering the motor or relays.
