Cadillac Repair: Horn-1988 Cadillac Deville, jumper wires, cadillac deville

Question
Bill--thanks for the help.  My husband finally found the relay under the hush panel!!!  How do we test the relay?  

Answer
Hi Janice, The easiest thing would be to remove another relay from the panel if there is one the same kind in the panel and plug it in the horn spot and then try your horn or else just buy a new relay and plug it in. Otherwise I'm not sure you would understand the procedure even if you had an ohmeter and jumper wires. However if you had a 12volt test light then terminal 1 and 5 should have power with the key on with the test light grounded. Terminal 2 will show a ground when you hook up the test light to battery voltage and push the horn button. And if you touched terminal 5 to 4 then the horns should play. Hope that helps. Bill
