Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Are you able to remove the glove box, and watch this area while another soaks the vehicle from the outside. An overflowing fresh air intake allowing water to come into the HVAC system and out the blower motor is a common concern. You may also want to seal around the fresh air intake using silicone to rule that out. Have you confirmed it is not the convertible top leaking above the visor?
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Hello again Chris here,
