97 olds Silh front blinkers work sometimes Sign In

Started several years ago and fixed it at the time with bulb grease. First left then spread to both front turn signals. This bulb is amber and behind a clear lens. It is also a running light so socket gets so hot it is fried,,,both sides same thing So if I greased them good they would work for 6 months or so. NOW<I greased them 3 days ago and they didn't work the next day already,,,then the next day they did fine.

What causes the socket to burn and char terrible? IF I splice the wires and change out to new sockets whats to prevent them from frying also?

On a 97 Olds Silhouette about 140K miles,,,I don't get it,,did all vans of this family have the same issues?

Nothing you can do about that. It's just a poor design.

Wonder if a LED turn bulb would solve your issue? LED use a lot less current and produce little heat. The only issue is the turn / hazard flasher may need modded or replaced with an electronic one that supports LED turn bulbs. If the socket is toast you're going to need to replace no matter if you use LED or not. No amount of grease is going to fix a faulty socket. Most the time the socket contacts become burnt from a poor electrical connection to the bulb. The resistance creates heat that melts the plastic that supports the contacts and deforms the contacts themselves. Bulb grease just helps protect the connection from moisture and corrosion. It's doesn't improve electrical contact. Most light housings are sealed, so the socket shouldn't require grease.

Off top of head do think if those are the common dash bulb just placed wrong and too hot there is the same in LED now. IDK - search for exact fit replacement probably color choice too. LED never gets too hot to touch for me - YET,

I was thinking they were common 3157 or 3057 bulbs. Was wondering if the LED bulb would work but I used to work at a car parts store for a while,,,most LED bulbs that went out the door came back in the door and broken returns

Are their better LED light brands than others?

In order to use LEDs you would have to change the flasher to a module and likely the tail light assembly itself. They sell kits for that but I wouldn't bother. Just replace the socket and grease the new contacts.

Does anyone know how this running light/ turn signal bulb gets grounded? Their is 3 wires out of this socket, dark blue, black and brown. They work so intermentally it may be a bad ground. When it is not working no amount of wiggling or taking bulb in and out helps

The black wire is the ground and the grounding point is #2 in the picture.

Re: 97 olds Silh front blinkers work sometimes-UPDATE Sign In

Update- so I changed the sockets hoping for the best. After getting done the right side worked as it should. Running light on, blinker working.

Left side the running light worked but blinker never worked. Cut a tad more wire off and recrimped thinking it just pulled out too far. NO LUCK there.

50 miles down the road the right blinker quit. Don't know when but I got home and got out to look and neither running light was working

So now I am back where I started but have eliminated the sockets and bulbs because those are new to socket replacing also.

There HAS to be a plug together connection back before it branches to BOTH sides that has dirty pin connections that change with the heat of under the hood as you drive. The sidelight blinkers and lights are completely in affected.

Any diagrams or schematics of wiring harness routing or connector locations appreciated. Maybe somebody else has similar issues?? or has worked on front blinker harness

Is power or ground missing at the socket?

At the left front turn lamp socket:

Brown= hot with parking lamps turned on
Light Blue= hot and toggling when left turn signal is on
Black= ground. Should be less than 0.3 volts drop to battery negative.

At the right front turn lamp socket:

Brown= hot with parking lamps turned on
Dark blue= hot and toggling when the right turn signal is on
Black= ground. Should be less than 0.3 volts drop to battery

This is not rocket science and there is no guess work required.

You simply test for power and ground at the socket and trace back whichever one is missing to the point it is being lost.

Re: 97 olds Silh front blinkers work sometimes-UPDATE Sign In

UPDATE---I was fooling around trying to see what effected it. Had the right blinker working when I pushed IN on the lever a lot like pushing the outside button for the cruise control. Blinker abruptly quit working.

I looked on AutoZone site and that module is $265 + change. I see used ones on E-Pay for 40. Then their is a cheaper knock off one for 60, think might be an Airtex. The AZ one was AC Delco AND their is another , I forgot who made it for 140 or so.

This module is blinkers wipers, washers, delay, cruise control resume set and on/off. In other words lots of functions and wires and pin connections. Their are NO guarantees that will fix it!!!

Does it PAY to take this off and inspect and spray the connections first???
