Sit in the driver's seat. With your right foot, kick sideways to the right. If that panel were not there, you would pretty much have kicked the device of which I spoke.
Once you have the panel off, it will be immediately obvious which one it is. A vacuum tester will be a quick way to check it. Mine was so bad that you could hear the air being sucked through it with the panel on and the motor running. __ __ Randy & \ \/ /alerie's \__/olvo '93 960 Estate
