I have a 2014 CRV. The front wiper sometimes working sometime not. I checked the fuse is good. I think that the relay may be going to die. However I couldn't found out where is the relay located. Would someone give me the diagram of the relays in the fuse box? thanks.

The relay circuit board is located in the under-hood fuse/relay box. However, that may not be the issue. There are several wiper related relays integrated on the circuit board (e.g, windshield wiper intermittent relay, windshield wiper hi/low relay, and windshield wiper motor relay).

Disconnect the 5P connector at the windshield wiper motor. Briefly connect direct power (+) to the motor's blue wire terminal (motor side), does the wiper run at low speed? Next, briefly connect direct power (+) to the motor's white wire terminal (motor side), does the wiper run at high speed?

If the motor runs when direct power is applied to it, then check for power on the disconnected 5P harness connector side. Turn the ignition to ON, then turn wiper switch to position 3-Low; with a voltmeter is there power on the 5P harness connector blue wire? Next, with wiper switch to position 4-High; with a voltmeter is there power on the 5P harness connector yellow wire?
