i was getting error message "brake light failure" and drivers side brake light was not working. i checked bulbs and bulb contacts which looks good, also checked wiring through trunk hood also looked OK. so i purchased brake light switch from pelican parts and replaced today which went smoothly, but still getting error message and now neither side brake lights working.
fuse is OK : (
i looked at the wire bundles in the trunk hood and they all looked OK
jb hey thanks
"you should have power at one wire constant, & power also only when applying the brakes.....on another wire." i have 4 wires behind the switch - what will the other 2 be doing?
also i dont have a test bulb handy, can use a voltmeter with 9 V setting (battery tester)? it also has AC and DC settings and mAmps...
hope youre enjoying your sunday
HOLY CRAP now the auto transmission will not move out of PARK - i think i actually saw a post when i was researching this that said something about the solenoid for the tranny connected to the brake switch ... do you know what happened?
this was what i saw before...
"PS The reason I had to replace my brake light switch was because my car was stuck in PARK. The selector was frozen in PARK because on the four pronged switch two prongs go to the transmission module. If that side of the switch fails the solenoid that blocks the shift linkage wont retract so you are stuck until you fix the brake light switch. FYI failure on the transmission side of the brake light switch does not give a message on the computer.
You can do a temporary fix to get the car home by pulling the gear shift lever off straight up and hard then pry up the trim plate to get at the ATM linkage. Turn on the ignition to activate the solenoid, move the selector then use a very thin piece of metal razor blade to keep the plunger in so you can get it past the Neutral indent. Just keep it in drive until you get it in your driveway."
i think the new switch may be bad...
