Where is the PCV location and why do my high beams turn on by themselves???

**elejes** · 03-22-2014

Hello guys,
I tried replacing the PCV on my 3.8 V6 2007 Grand Prix after a tune up and could not find the location of the PCV. Does anyone know where its located? Also, my high beams turn on by themselves, especially when I have the left turn signal switch on. The minute the switch automatically turns off as I straighten the steering wheel the high beams turn on. I usually tap the turn signal stick and they come off. Heck sometime the cars light turn off completely and I have to turn my high beams on so I can see. Any help would be appreciated. Thinking its the actual signal switch, but figured someone here knows best. Thanks!

Sounds like the multifunction switch is shot.

PCV is under the MAP at the pulley side of the engine.

It's located on the passenger side between the alternator and coil pak,it will have a vaccum line to it, next to the map sensor. As for your lights, I know nothing about electrical systems, sorry.

Be careful when you twist the MAP sensor off, the plastic clip on it is brittle, and if you grab it the wrong way you can snap that clip... trying to put it back in, too. Just be gentle. When you get the MAP off, the PCV will be right in that hole, just pull up on the little nipple sticking out. Make sure the O-ring stays in place unless you are replacing it, I dont think new ones come with an o-ring.

Ohh cool! Thanks guys, that was quick. I will be ordering the turn signal switch from Amazon and replacing the PCV plug. Thanks again for all the help!
