I believe our vans have what I call a horn relay or regulator, if that's what it's called. Anyway, if there is such a thing as I believe, does it do anything other than work the horn? The reason I ask is this...I have had an electrical short for some time. If I leave the battery connected something drains the battery, thus I put a quick disconnect on the battery cable as a temporary resolution. While I was working on the van this evening my hand touched the "horn relay" and it was HOT leading me to believe that I finally found my short. I had also noted that whenever I reconnected the battery cable disconnect I would hear a faint "click" which I believe came from the relay. I disconnected the relay and within minutes it was cool to the touch. So...back to my original question. If in fact there is a horn relay and I disconnect it, am I disconnecting anything else? And my horn has not worked for some time so I couldn't test the relay connected or disconnected to see if there is any difference. The "relay" resembles a solenoid and has two screw-type connections and a plug-type connection, which I unplugged. Hope I was clear enough. Thanks in advance!

The thing with the horn relay on these is that they are the junctions for all of the power feeds usually. I wouldnt think it would be to tough to come up with a new one from an auto parts store. chevy must have used them on tons of stuff.

Like Digz said the screw terminals are for the power feeds and the plug is for horn. You can get new ones, I have seen ones with connectors for the plugs or with screw termanas for horn wires. You can check your horn by jumping from the red wire to the green that goes to horn. Your spring washer under horn button might be getting worn(weak) & is making contact all the time.

Does the horn relay have to be grounded on the doghouse???? I have it unbolted and I accidentily bumped it on the doghouse and got sparks..... Grounded?????

malibusurfer,
It "Does" need to be grounded. I thought it didn't on mine but found out the hard way!! Yeah! lots of sparks and 2 blown fuses.... I was told it didn't but learned....

Does anybody know, off hand, the part number for the stock horn relay?

Thanks!!!

Heres something to also check- as Ive had this happen many times. Check the Positive feed wire @ alternator-In the dark! If the diodes inside are bad it(alt.) will drain the battery. Disconnect the red wire@ the alt. - then see if (in the dark) with a flashlight using to locate the terminal- if there is a spark?? if so =with everything turned off - the alt is at fault. You can also try just disconnecting the same wire- covering it up - and leaving the van sit for a day or 2 & see if it starts up?? No drain on batt - & caharged batt - should not drain off the battery- hope this helps. By the way -the diodes are replaveable in teh alt as a unit- just in case youve spent big bucks on a alt.
