1999 Lincoln Town Car body & structure problems

Tl* the contact owns a 1999 lincoln town car. The contact stated that while driving the contact felt the brakes were not working properly. The contact made a right hand turn and crashed into a parked truck. The contact did not have an injury that required transport to a hospital and no police report was filed. The crash happened right at the independent mechanic's shop. The independent mechanic fixed the brakes with a fluid leak from the brake line as the cause of the malfunction.

During every rain water runs down the inside of the firewall on the passenger's side, behind the glove box, soaks the front carpet, and stands as much as 1 1/2" deep in the rear floor. Both carpets were very moldy. I have taken the car to dealers, body shops, and windshield glass experts, and nobody can fix it. If I run a small stream of water from the hose on the lower right corner of the windshield it will show up on the inside of the car within a minute.
