To find it definitively:
1. Consult your owner's manual: This is the best place to start. It should have a diagram of your fuse box(es) showing the location of the wiper relay. The relay itself may be labeled or you may find a legend explaining symbols used.
2. Check the underhood fuse box: This box is usually located near the battery. Look for a diagram inside the fuse box lid. It might be labeled as "Wiper Relay," "Windshield Wiper Relay," or have a symbol representing wipers.
3. Check the interior fuse box: The location of this varies, but common spots are under the dashboard, on the driver's side, or sometimes in the glove box. Again, look for a diagram or labeling on the fuse box cover.
4. If you cannot locate it visually: Use the owner's manual to identify the relay number or designation, then visually check the corresponding relay to see if it matches the description. If you still have difficulty, it's best to seek assistance from a mechanic or automotive electrician.
Remember to always disconnect the negative battery terminal before working with fuses or relays to prevent electrical shorts or damage.
