Where is the wiper relay in a 2003 honda odyssey

Your vehicle might not have a flasher relay.

Vehicles using a CAN-bus system often use a single ECU to carry out all vehicle functions where timing is required - flashers and hazard flashers, courtesy light, wiper delay, etc.

I suggest you check a wiring diagram for your car to discover what system it has.

Check your owner's manual; a full detailed schematic of the fuse box (under the dash) and power distribution panel (under the hood) is diagrammed. In absence of your owner's manual, try downloading one online or visit your local Honda dealer for a printout.

Put the right side wiper on only. Turn on wipers. When the wiper moves all the way to the left and starts to go back to the right turn off the ignition with the wiper switch still on. Remove the right wiper arm and install the left wiper arm in the far left of the wiper movement. Turn on ignition and allow the left wiper to go all the way back to it's rest location at the bottom of the windshield. Turn off ignition and install the right side wiper arm. This will give you a start to properly set the wiper arms.

Thanks for choosing FixYa and welcome to the site. It sounds like your wiper switch is messed up. I would advise you to check the wiring. If there are no loose wires, change your wiper switch.

the clogged breather port of wiper motor causes the motor not work

Hmm i would first take a trip to the junk yard and replace the switch. Just in case you don't know they suppose to last few seconds before stop. Inspect the wiring, replace wiper motor if switch won't work.

Relays should be located within your fuse panel, generally located along the side wall under the hood. They are Larger Square pieces that are plugged into the panel. The cover to the fuse panel may label each individual relay and fuse for their respected use, but it might be too dirty to read or worn off. In which case look in the back of your owners manual. That gives a list of each fuse and relay and their purpose.

sounds like its loose on the shaft
remove & inspect shaft
may just need moving to original park position and retightening

I assume you mean the front or rear power accessory sockets. You will need to check two fuses. 1) Fuse no. 8 (7.5A) in the drivers under dash fuse/relay box. 2) Fuse no. 9 (15A) in the passenger's kick panel fuse/relay box. Both these fuses must be good for the accessory sockets to have power.
