Mercedes SLK R170 fan blower temperamental

The fan blower in my SLK seems to be very temperamental, it will work for a few seconds then cut out, start working again-usually after going over a bump in the road for example.
It usually seems to carry on working for a while until it cuts out again, it’s worse when the car is cold, obviously with it being winter at the moment I’d like to have a reliable heater!!.
Has anyone else had this happen on theirs?, or is there a common issue with them?.
The blower motor itself seems fine when it’s working and will work at whatever fan speed you set it to but it’s like a bad connection or something it keeps losing power and stopping and starting.
