A90 Quattro Sept 1987 Saloon
The windows keep steaming up even when the car is sitting idle for a
few days. In cold weather there is a lot of condensation on the inside
When driving in wet weather the windows also steam up and takes
forever to clear. The side windows are usually permanantly steamed up.
Heater and blower ok and air blowing to and through the relevant
vents. Heated rear window working but appears slow to demist.
The only solution so far is driving with windows open for a time.
Any help will be greatly appreciated.
