1. Drive the 325is to your garage or a parking lot. Turn the fan on and feel for any air coming out the vents. If there is no air, then the blower motor needs to be replaced. Put the 325is into Park, then engage the parking brake so there is no danger of gear slippage during the repair. Make sure you have room to maneuver around the front of the BMW for the removal process. Turn the BMW off and open the hood and trunk. 2. Go into the trunk of the BMW and disconnect the negative battery cable from the cars battery. The battery is located in the trunk of the 325is for better weight allocation. Go around to the front of the 325is and prop the hood up with the hood prop stick. The blower motor assembly will be mounted with six screws against the rear firewall. Remove the screws with a Phillips-head screwdriver and pull the blow motor assembly off the firewall. 3. Press the pressure clips on either side of the motor and pull the motor from the blower assembly. If the blower motor has...

1. Add the oil-based dye, supplied in the kit, to the power steering reservoir. The reservoir for the Audi A4 is located on the drivers side inner fender well, just in front of the windshield reservoir. Test-drive the vehicle for 10 minutes to circulate the dye and load the power steering system. This will force small leaks to show up. 2. Use the black light, supplied in the kit, to search under the hood for leaks. Start at the power steering reservoir, following both the small return hose and the larger supply hose to the power steering pump and the rack and pinion steering gear. Note any leaks found. 3. Raise and support the vehicle using the floor jack and jack stands. Then, from underneath, inspect the power steering rack and the power steering hoses. Note any leaks found.

1. Pull up the fuse panel release lever to pull the fuse panel down and open it. 2. Look for the brake light and cruise control fuses using the diagram located on the back of the fuse panel lid. The problem could be simply a damaged or burned out fuse. 3. Check for a rough feel in the idling position and sucking sound coming from the engine bay. This means there is a vacuum leak -- a hole in the intake hoses that is allowing additional air into the system. This will adversely affect the cruise control. 4. Look at the throttle cable to see whether it is fraying or in disrepair, as either of these will keep the cruise control from controlling the throttle properly.
