Had these codes for a long time but want to sell the car so its time to address. Figured I'd post up some of the things I discovered for others.
I checked the manual and found the system consists of a few things. Valve, pump, hoses, vacuum line, a few fuses, and a relay. I figured they would all die with the same problem but when I googled looking for the most common issue, I basicly found a bunch of people saying the dealer swaps the pump or valve and then they have to go back for the other a week later. Seems the dealer charges in excess of 1000 bucks for this. What a crime if you ask me. to replace both parts would take maybe an hour for an amature.
I havent actually fixed this yet but I'll show you what I have found thus far and I have a pump on order...I'll let you know if it fixes it later this week.
First thing I did was a quick visual inspection, checked the fuses and tested the relay. (testing is easy with some scrap wire and a 12v light bulb...but its really cheap so if your worried about testing...just replace it.) Everything seemed tight and intact. Fuses and relay were ok.
Next thing was I tried to test the pump. I consulted this wiring diagram and supplied 12 to the connector..I figured whats the worst thing that could happen if its bad anyways..haha
I jammed some wires into the plug...(This pic is from later after I removed the pump...but you get the idea) Positive on the left...(The plug from the car has gray and black...both with yellow stripes but on the pump side its old fasion red and black)
added some power
...And nothing happened.
So I dont know how effective this test is but I assumed its the pump and started moving that direction.
When I removed the pump, about a cup to a pint of water came out. so I think I'm on the right track. I decided to take apart the pump so I could see if I could figure out a way to fix it...(Yeah...the part is on order now..lol.) Since that didnt pan out...I'll post the pics anyways so you can see what it looks like inside.
I had no room so i setup my testing right underneath my car..lol
Here is the pump with the bracket removed
Bolts were seized on so I drilled the top and knocked off the head with a chizel
Its pretty east to pry apart
What a mess! I still cant figure out how water gets in this thing. I was suprised to find it still spun freely
Continuing on to the back...
Just as messy on this side
At this point, I added power directly to the motor and it didnt do anything so I'd say my first test was valid.
I have a new part on order from rockauto...cx2032 It comes with the pump, bracket, and hoses for the same price as cx2036 which is pump only. Paid just under 150 shipped.
I let you know what happens when I install the part next week.
