Just a little update. Yesterday my son and I changed the motor oil and rear diff oil. The weather turned bad so we had to stop. The oil looked surprisingly good. There is a little creamy gunk on the dipstick, but the oil itself was normal. Not sure if it had something to do with it being a fully synthetic oil. I've seen conventional motor oils turn to solid cream with some water in the block.
Today I removed the headlights and baked them at 175 in the oven for an hour. The flooded headlight is losing it's chrome inside, due to the ice I suspect. It will need replaced.
I had a high engine idle problem after the drowning. It wanted to idle at 1500 RPM. I took off the throttle body and cleaned it thoroughly. I took apart the Idle Air Control Valve and removed the TPS. I found the IAC stuck open with black build up. I sprayed some cleaner in there and got the valve free. I reinstalled it and the idle went back to normal. Good thing because a new IAC is $220 aftermarket. I also cleaned the MAF and both O2 sensors. As an added measure I warrantied out the TPS.
The speedometer and cruise control was a different story. I removed the cruise control and ended up throwing it on the ground in the sun. I meant to go buy a T20 torx bit and tear it apart and clean it. I ran out of daylight and reinstalled it. I even tried to remove a sensor from the transmission. It turned out being a wiring harness that goes to the valve body. Miraculously, when I reinstalled it and drove it away, the speedo and cruise were working.
Tomorrow I am going to try to take the ABS module off of the pump and spray it out with electrical cleaner. I may meter out the various resistors in there and replace any I find burnt out. With a little luck I can save the ABS pump. They are not cheap! I am also going to remove the seats and pull out the carpet. Maybe Sunday I can pull the right front door panel, tear apart the window motor, clean it and get it working again.
Total cost of repairs so far: $15 oil and filter, $20? for air filter, $40 for a new pair of Silverstar Ultra headlight bulbs. Oh yeah, $15 synthetic gear oil.
