Window motor or regulator?

[HONEYMON57ER]

Hi,

      It was -2c this morning and windows frosted shut. I don’t drop the windows until defrosted but as soon as I opened the door

      there were 5 loud thumping noises coming from door down near where the Bose speaker lives. After the windows defrosted

      I tried the switch and nothing. Not sure if this would indicate motor or regulator or even just the switch? From the noise I would guess 

      It’s the motor but the window still drops and lifts properly on opening/ closing the door? Anyone had this before?

 

thanks Barry

for future reference Gumipfledge on your seals and run a credit card between glass and seal before opening car. If the window is dropping and raising correctly when opening and closing the door, then the regulator and motor must be OK as long as it is the same amount as previously? Sounds to me as if the switch has failed, not unusual but cannot explain the thumps unless the cables were a bit loose and the slack was being taken up by the ratchet.

Thanks for the reply. If it’s just the switch it makes sense as it had been playing up a bit since I got the car in August.

it needed 2 or 3 attempts to work.
