jboymechanic Posted March 3, 2011 Share Posted March 3, 2011 I have a '95 Legacy wagon that is acting strangely. The turn signals, hazards, and parking light functions all work properly other than when I press the brake pedal, then the right/driver side turn signal stays on/stops flashing. The indication in the gauge cluster stays on as well, not sure about the rear tail light/signal as I was alone and couldn't see it. The car does have a 4 wire plug for a trailer that was not installed by me if that helps. What could be going on here? Link to comment Share on other sites More sharing options...
Allpar Mod Posted March 3, 2011 Share Posted March 3, 2011 Sounds like a short. The trailer plug could be the culprit. I have experience with trailer wiring on both ends and if care isn't taken on installing trailer wiring to head off corrosion, it happens and badly. That could easily be causing the issue you describe. That's where I'd start. Link to comment Share on other sites More sharing options...

What could be going on here? first guess is a bad bulb. remove each bulb, one at a time and then replace, and test the system, starting in the rear, to see if it still has the same problem. when you remove the bulb that eliminates the problem, replace it with new. dual element bulbs can cause screwy things to happen if one bad element touches the other element in the bulb.

jboymechanic Posted March 4, 2011 Author Share Posted March 4, 2011 Well, I haven't even started driving the car yet, so it's been sitting for a couple of months waiting for warmer weather to do a head gasket job. Wondering if the critters are chewing on my wires? Link to comment Share on other sites More sharing options...
Rooster2 Posted March 4, 2011 Share Posted March 4, 2011 Well, I haven't even started driving the car yet, so it's been sitting for a couple of months waiting for warmer weather to do a head gasket job. Wondering if the critters are chewing on my wires? Been sitting......quite possible mice have been chewing on the wiring. I have seen that before. Also, had goofy lighting problems on a Toyota, turned out to be a cracked bulb socket holding the brake/turn signal bulb. Your problem is either bulb or wiring. Like someone said, try replacing bulbs first as your first repair approach. Link to comment Share on other sites More sharing options...
Cougar Posted March 5, 2011 Share Posted March 5, 2011 The brake circuit passes through the turn signal flasher I believe. Unless the wiring for that side has been bypassed somehow I would have to thing the trouble is with the flasher unit. It would be interesting to know how the emergency flashers work along with the brake light. Link to comment Share on other sites More sharing options...
nipper Posted March 5, 2011 Share Posted March 5, 2011 #1 reason, the trailer adapter. #2 is a bad bulb that has shorted out and is backfeeding. Link to comment Share on other sites More sharing options...
jboymechanic Posted May 10, 2011 Author Share Posted May 10, 2011 I finally got around to fixing this as I've been driving the car more regularly. The end of the trailer wiring was shorted out. Cut the wires and taped them off, no more issues. Link to comment Share on other sites More sharing options...

You will need one with the turn lenses being separate than the brake lens, to combine them ot the trailer light. Could be a ground issue. Link to comment Share on other sites More sharing options...

Nope, the wires were spliced into the left tail light with connectors, that was sure not a U-Haul install for sure. Link to comment Share on other sites More sharing options...
Ricearu Posted May 11, 2011 Share Posted May 11, 2011 Sounds like a texas uhaul install. (used to work for uhaul and had to fix alot of wiring under warranty by a few goomba's that used ttaps from the kits. I always cut back the insulation and soldered them in, then taped over very orderly. NEVER had any returns. Link to comment Share on other sites More sharing options...

Yep, that is how my Dad wires in trailor lighting, Solder is the best way to make sure nothing gets in. Link to comment Share on other sites More sharing options...
MilesFox Posted May 11, 2011 Share Posted May 11, 2011 just eliminate the trailer harness as it is the wrong type if it is a 4way flat with no converter box. The pigtail grounds to the chassis, but the lights ground at the switch. Link to comment Share on other sites More sharing options...

The problem with trying to remove the harness from the tail light wires is all the wires will be cut in half, as someone used those blue connctors which make one wire into two, so when you crimp them, it slices the wire and is a PITA to remove without messing everything up.
