howl coming out of a/c on the outside
 

I went camping this weekend and it rained very hard. when i returned from going out to eat, the a/c unit(dometic) was howling on the outside, but still blowing cold air, has anyone else had this problem? I turned it off until i could check it out so i wouldn't damage anything more than what could have been done.

The fan motor bearings may need lubed, or there is something rubbing inside.

thanks, i'll check it out when it cools down under 90.
