I have a Mk1 Golf Cabriolet with an hydraulic roof. Today I went for a drive and whilst the roof lowered as normal, I could not raise it again.
I checked the fluid levels and they're fine.
There is no sound coming from the pump at all. The only sounds I can here are from a bank of 3 relays.
One relay triggers when the up button is pushed, one when the down button is pushed. I am unsure what the 3rd relay does as it makes no noise.
I unplugged the pump and connected a multimeter to the socket it connects to and got 9.5 volts (car engine not running).
So, there seems to be power coming to the pump but nothing is happening. What could be causing this?
Any ideas would be great!
