85 Seville right blinker causing hazards to come on

[michael chambers]

Does anyone have an idea on how to solve this?

The tail lights, the brake lights, the hazard lights, and the LEFT blinker work just fine. The right blinker causes both blinkers to come on (and blink fast!)...only in the back. The front ones work fine though.

I replaced the bulbs on 2 out of the 3 lights. When that didn't work, I replaced the entire socket of the middle one (I suspected it was the culprit because the light in it was the first one burnt out.)

Thank you.

Tried replacing the turn signal flasher? Im used to having the turn signal/hazard lights on seperate circuits, but I know some older cars had them on the same circuit and thus used the same flasher. Worth a shot, they're only about 5 bucks a peice.

I thought about trying that, but I figured since the left one works perfectly, it couldn't be the flasher. I WILL try it though, seeing as they're cheap. Thanks

That didn't work. Any other ideas?

Only other thing I could figure would be the turn signal switch itself. That or a crossed wire or two somewhere along the line.

I should have mentioned this before, but the parking lights in the front are also out. The bulbs are good, but every time I put a fuse in,it pops (now matter how many amps). Could that short be related to this, or is it just a coincidence?

Yes it could be related. With an open circuit (fuse removed), GM wiring can feed back and cause other things to be powered along with the circuit you selected. Popping a fuse quickly means a short to ground. Investigate the front two park lamp bulb sockets and wiring for a dead short. I would suspect the passenger or right side as the culprit because that causes fast blinking which is an indicator of poor ground. Look for the two terminals within the bulb socket to be touching or the ground wire touching. Or it can be as simple as a faulty bulb where the two filiments are touching inside the bulb. Or a faulty turn signal switch, but unlikely. The Seville used a relay in the trunk for each side center brakelight bulb. This relay is specific to the Seville itself. But, Fix the short then see if the problem goes away. If I recall, this car has two lamp assemblies under the headlights that are amber, but only the outer one has a dual filiment bulb to enable the turn signal. The inner one just stays amber and has a single filiment bulb. This is from memory so bare with me! I do know for a fact the Seville used a relay or diode to power the center brake bulb, one on either side in the trunk. Many people removed the center bulb in later years rather than replace the relay.
