Yes, your water drains are probably stopped up with leaves, etc. 
What year do you have?

If you don't fix this the water will destroy the car. It is easy to fix, 
but I need to know the year to tell you how.

It can be either the speedo cable or the speedometer itself. It can 
be hard to tell the difference. If you disconnect the cable from the 
speedo head and it still makes noise then the cable is obviously 
the problem, but if this stops the noise it could be either since you 
have disturbed the cable and changed the load on it.

There is an adjustment that should be made to the cable that 
almost no one knows about that you should try: Make sure that 
your cable has the cotter pin or circlip holding it to the grease cap 
under the LF hubcap, then slide under the car and find where the 
cable exits the inside face of the steering knuckle. Grab the cable 
firmly and pull it inboard, then push it outwards. It will slide with 
difficulty through the rubber bushing in the knuckle. Once you have 
gotten it to move, push it in, grab it with your thumbnail against the 
rubber bushing and pull it out. Look at the space now between the 
bushing and your thumbnail so you can see the total amount of 
"play" there is. Now push it half way back in. This makes sure 
there is no stress on the cable in the installed position. This 
adjustment MUST be done with the cable fully installed in the 
speedometer head.

If the problem is with your speedo head, I can probably rebuild it 
and cure it, but you should exhaust the other possibilities first.
