CONDENSATION. My car is full of it. Why? What can I do about it?
The only reason for condensation inside the car is moisture inside the car and that usually means a leak.
Could be rainwater coming in through the pollen filter because the waterproof cover is not installed correctly.
Could be blocked bulkhead vent well drains leaving rainwater nowhere else to go except into the car.
Could be failed damp-proof membranes inside the doors.
Could be failed door edge seals.
Could be a failed front or rear screen seal.
Could be failed metal to metal joints in the assembly of the car (many of which are glued rather than spot welded together).
Could be a missing bolt (recently the case with a VW Polo).
Could be the pipe has popped off the rear washer jet.
Could be failed rear lamp cluster seals.
Could be an a/c condenser fault allowing condensate to drip into the car.
If it has a sunroof, could be failed seals or blocked drains from that.
