Aug 31st, I left south MS heading to see my family in Jacksonville, SC (850 miles)….not 15 miles into the trip it starts to drizzle some. I bump the wipers just to do a quick pass of the wipers, they go up but then only go half way down. If you hold the wiper lever all the way up or all the way down timing your release just right, they will go home. High/low works normally, intermittent/mist is the issue…..no big deal, that 5mins is the only rain Ive had so far.

Sept 3rd….we were heading to Myrtle Beach to visit a car museum, got about 3 blks the street, when the “service abs, service active handling, service traction control” lights came on. Arghhhhh!!! Turned around, went to the local Chevrolet dealer (Marine Chevrolet) to have them look at and possibly fix the issue. They call that evening telling me that the brake pressure modulator valve for the ABS is bad. Says it would take a week to get it and for everything it would be $2200! I told the guy that I wasnt gonna be in town that long and I’d just have to take it to my local dealer once I get home. He did give me the GM part number though. i couldnt find one myself thru a dealer but found a NOS one on ebay for $820……everywhere else was $975 reman or $1000 for aftermarket.

So if you guys ever run into this issue, be prepared to hunt and when you find it, be equally prepared to pay through the nose for it.

 

I’d be wary of ANY dealership diagnosing your car so before you start spending money on an unneeded part I’d get a second opinion and not from a dealership…what does the dealers RO say on it ??…maybe you can post a picture of it ??…dealers make their money CHANGING parts and not diagnosing them…any trouble codes ??

 

All this, assuming the diagnosis at the dealership is accurate. I’d want a second professional diagnosis before I’d source a relatively expensive part for someone else to install. The risk is that if your supplied part doesn’t fix the problem, you’re going to be out the cost of the part and the cost to have had it installed. BTW, what fault codes were thrown?

 

The picture is what they said about the issue. Found code C0131.

 

Not to much info on this DTC…here is some info from Service Info but I’d still have another shop look at it…price is pretty steep for OEM…as usual per your RO the dealership follows their “flow chart”…they can’t think for themselves as far as diagnosing.

 

As many electrical glitches as these cars have and seeing that the warnings didn't come on for the dealership, I wouldn't do a thing. Just wait and see if it happens again. Things as unrelated as a loose plug wire can throw those codes.
