Which one ? do you know ? The body control system consists of the following 3 modules: • The Dash Integration Module (DIM) • The Instrument Panel Module (IPM) • The Rear Integration Module (RIM) Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each module is connected to the Class 2 serial data circuit, many of the control functions are implemented by Class 2 messages.

The transmission sounds like it was over-filled. - you must always check the fluid level only when the transmission is at full operating temperature. The fluid volume increases a lot as it heats to operating temperature, and if overfilled, will come out the filler tube. To avoid seal problems, I would take it back to the mechanic and ask him to remove some of the fluid to bring it back in line with the dipstick markings.

Clogged lines or spray head . No power or ground to washer motor .

here's a way to check for leaks assuming your not in minnesota and its 30 below zero. Fill a spray water bottle with water and then put a teaspoon of soap in the bottle..shake. Squirt the soapy water onto the air fittings to test for leaks. If the fitting bubbles up, then you have a leak. In that case, tighten the fitting with a wrench, or remove and reinstall the fitting with thread sealant. Undo the fitting with a wrench. Apply two wraps of Teflon tape around the fitting, then tighten the fitting and test again. If the fitting still leaks, you may have a cracked fitting. Replace the fitting and reinstall, then test again. Hope this helps.
