I recently had the blower fan replaced (it was inoperative) and since then have a problem with water leaking onto the floorboard. This is exacerbated with rainfall however leaking occurs even without rain, most often when making left-hand turns.
The fan does not need to be turned on though when it is the leak is even more prevalent, perhaps forcing the excess water out?

Additionally, when the fan is turned on and making a left turn, the fan 'squeals' and the output of water is increased.

How can I prevent water from entering the blower fan to preclude the leaking on the floorboard and ruining the fan? :confused:

I thank you in advance for your responses.

My first suggestion is to take it back to the place that fixed it for you and let them figure it out.

Other than that, check to make sure that the clamps were put on the heater hoses where they attach to the core.

There is no reason that you should suddenly have leakage after having the blower motor replaced.... it was just the blower motor, right? Did you have the whole heater core replaced?

mightymoose_22,

Thank you for responding.

Taking the car back to where the repair may be a bit of a problem since I had it fixed 450 miles away from where I live.

I only had the blower motor replaced, not the heater core. If the hoses were disconnected from the heater core I would suspect that either I would have not heat (which is not the case) or there would be an overwhelming odor of antifreeze. Please correct me if I am wrong.

I will check the clamps to ensure they are secure...as soon as my floor board dries up a bit ;-)

Is that the only reason water would be in the blower motor? Could there be leakage elsewhere that I need to look for?

The clamps are actually under the hood on the firewall.

What it seems is that you have a leaking heater core. Replacing the blower motor should not have cause any leaking... however if they were a bit rough down there I suppose they could have cracked something and got it going.

Replacing the heater core is an ugly job... haven't done it myself, but have heard horror stories.

There really is no other explanation for a leak in that area. If it was just a motor replacement then there is no reason they should have loosened the hose clamps... my guess is the heater core.

If you are real lucky and are able to find where the leak is coming from then you may be able to patch the leak from the outside. Odds are that you will need to replace the heater core.

The temporary fix to the problem is to disconnect the input and output hoses from the heater core and join the together, bypassing the heater. You will not get any heat, but you will not be leaking either.

blower fan nothing to do with leaking. i'd guees your heater core leaking escorts are bad for heater cores. is it leaking inside on floor or where moter goes?

I can see how a build-up of leaves in the cowling would reduce the airflow, but the last person to post in this thread (http://www.automotiveforums.com/vbulletin/t426775.html) was pretty emphatic that it was also causing rain water to leak in, so you might want to check and see if the cowling is clear.
