Corroded connector in cabin causing warning lights to come on. FIX: relocate it
I guess I'll just start one thread about all the different problems I've had on different cars that had corrosion issues at a certain wiring connector. Maybe a grown up(admin) can merge my other post's when I figure out where they went? The connector with the problem is behind the Left kick panel. Right at the bottom. (I dunno if it'd be in the same location for a right hand drive car?) They had recalls at one time to put a plastic shield in there to deflect water or something but either it didn't get done on these cars or it didn't work. If you relocate the connector before any sign of problems you may save yourself some headaches down the road.
One 2015 Mirage had the abs and brake warning light come on randomly, the traction control light would stay on randomly as well. The brake lights at the rear of the car would randomly come on and pulsate when the key was in the run position. It would throw an error code for the brake light switch. The dealer replaced the switch and kicked it out the door. It didn't fix it, I brought the car back and they wanted to order a new etacs for around $1000 and hope it'd fix the problem. I told them no, picked up the car and replaced the connector.
Another car 2015 had an airbag light on constantly. The trouble code stored was for the lh front airbag impact sensor. I swapped the sensors right to left on the rad support. The same code re-appeared. I removed the Drivers side kick panel moving the connector a little in the process. This caused pretty much every warning light on the dash to come on, the car would barely run. Cut the connector out of the harness and soldered the wires together. Fixed.
Had another 2015 last week come in with the brake warning light on. This one was the worst I've seen so far. One pin in the connector was completely corroded away and a few others were in pretty bad shape. I was really surprised this car didn't show any other problems.
Today I got told about 2 more cars. This time 2017's. Both have the low washer fluid lights on and one car has the brake warning light flickering. IIRC the one car had the same problem about a year ago and the dealer was clueless(big suprise). They said they ordered a new speedo cluster and would call when it came in. Well, I forgot about it and the driver at the time said the lights went away eventually. But now they're back. Now the car is past warranty. I'll just fix it myself, it's just far less hassle than dealing with our dealer's incompetence.
I'll add some pics here eventually. One note though if anyone ever replaces the pigtail or cut the entire connector out. Do one wire at a time. The colors don't match up on some wires and many of the wires are the same color with the same tracers just to make it more complicated. Oh and I found a couple that weren't even used and taped them off.
