I wrote a topic if I should buy a saab this week, got advised not to but i couldnt resist, it has only a braking problem, the owner told it was the servo, but i found out that is the pump that keeps blowing the fuse
what is this problem?
It's a problem where the fuse keeps getting blown because the amperage exceeds the rated amperage of the fuse.
Seriously though you're going to have to give a bit more information than that. The problem could be a number of things. As an example, if the pump IS faulty as you say it is then it's quite possibly going to be drawing more current. More current in the circuit mean bye bye Mr Fuse.
Have a look in the archives. (Only a couple of weeks ago). Someone had a Pump replaced for a few hundred quid including a replacement pump. Don't go to Saab cos they wanted £1700 & a large tub of vaseline to ensure the shafting they give you, gives them as much pleasure as possible!!
