The transmission on a Saab 900 is mounted directly on the bottom of the engine. That clanking is likely coming from a broken tooth on a gear.
Bearing in blower motor?
check the cadillidic converter under the car.
alot of times people mistake a tapping or thumping noise under the hood is the engine, when it is actually a purge control motor on drivers side fender. find it and see if the timing to your taping is the same. good luck.
If by motor you mean the engine. If the car is running and it's not making much noise turn in the a/c in the car and if the noise gets worse I would replace your air conditioning pp
There is a problem with wiper transmission which is what moves the arms & is under the cowl.
Not enough info. What kind of noise? Coming from where? Under what situation(s) does it occur?
Fresh air vent motor
Most common culprit is a slipping belt.
that could be a variety of things, wheel bearings, u joints, rear end...
grinding noise from the fan is a bad bearing on either the fan or the water pump.have it checked before it lets go and goes thru radiator
The noise can be comming from the weather stripping around the door, the wind passing past the antenna or from the wind around the luggage rack on acceleration.
its the hvac blend door motor crunching up the doors if you have the digital climate control
