Thread: wet pasanger floor on 04

Take a look at this. I think this fits the 04+ as well.

Theres a TSB for the 04 and wet passenger side. My mom has an 04 and I sent her to a guy who fixed it for $20.

HUH? I don't have an overkill pcm.

I like it a lot... told him what I wanted/needed and haven't had any problems. Definitely woke the car up and gives a slight advantage over stock tune supercharged GP's.

You'd get out cheaper and with less headaches if you did the SD/SSAC headers and sold your DP.

I just ordered a plog the other day... Tuesday in fact...

I'll just go ahead and recommend that you never turn the car off with the vents on the "floor" position - set it to blow on the face.

I kinda had this happen to me, except that the water never made it to the floor. What happened a couple winters ago was that ice built up under the passenger cowl and allowed more water to come in. It leaked down into the blower motor and settled on the plastic trim piece that hangs underneath. It then froze and pushed the armature upwards, eventually leading to the blower motor burning out completely. The week following was the coldest of my life...
