Hi, the relay for AC compressor/Horn are on the left as you look at the car from the front. in the middle are Blower/Hi/Low and On the right,Engine Fan High Engine Fan Low. You may have more or less relaysand they may not be in order.
They are located in the Power Distribution Centre under the hood up near the wipers on the left. The fuses and breakers are on top and the relays are on the bottom.
Find the horn relay because its reasy to honk the horn while you pull the relay that completes the circuit. The one that is dissconnected and the horn wont blow is a good relay. Check the power rating in Amps and switch with the fan relays. You can find the fan by unplugging the coolant temp sensor. This will make the fan run all the time on High Speed (a good temporary fix for traffic jam overheating) and unplugging relays untill the fan stops running
Good Luck.
