Smoke coming from a hose on the passenger side that goes through the box that holds the wiper motor and into the firewall. There is a valve of some sorts that is spliced between the hose...I wish I had taken a photo of it. I put a mirror around it and didn't see anything. There is no wiring and it isn't comig in from the engine bay. It has to be around this valve and hose, but I couldn't tell where or why. It went away after driving the car about 5 minutes, parking and looking again. puzzled?
