The power locks on the driver door will open the lock but not lock it? The other buttons in the car do all the functions they are supposed to. Also the key unlock all works via the driver door key. Any ideas or is it likely the switch?
The wiper fluid is not working. No sound when pressing and fuses appear ok. Likely the pump or switch? Any advice on how to get under the shock tower to test the voltage to the pump?
Before I do any first changes... Has anyone found that synthetic oil, trans etc or maybe additives have performed best with this car? It is the simple 3.0.
Thanks in advance,
Sounds like a bad left power lock switch. Disconnect the switch and with a test lead hooked to a good ground, ground the PK/YL wire. The doors should lock. Ground the PK/LG wire. The doors should unlock. With a test light hooked to power instead of ground probe the BK ground wires. The test light should illuminate. If all of these things happen then you have a bad lock switch. If not then first check the door wiring in the door jamb boot.
The WASHER pump can be accessed by partially removing the R.F. inner splash shield. Should be a few screws here and there. Using a test light hooked to ground probe the BK/WT wire and have someone hit the washer switch. The test light should illuminate. If it doesn't then check fuse 17 on the fuse panel inside of the car. Otherwise, the most common thing is the multi-function switch (wiper/washer/turn signal/high beam switch). Also with the test light hooked to power probe the BK wire. Test light should light. If the test light illuminates both times then you have a bad pump. Make sure you don't have frozen washer fluid.
As far as synthetic fluid, at 104,000 mi. I'd stick with conventional stuff or go with a synthetic blend for higher mileage. The higher mileage stuff has seal conditioners and additive to prevent excessive consumption.
