Fuses And Circuit Breaker problems of the 2001 Mazda Tribute

When driving at highway speeds speedometer goes up and down. When driving and letting up on accelerator pedal, vehicle shifts into lower gear. Feels like brakes were applied very hard. Vehicle taken to dealer 3 times, cannot find cause of problem. Consumer states the cluster gauges are erratic, then the transmission shifts long or slow, on three different occasions, the transmission shifted from over drive to first, when letting up on the gas pedal it felt like the brakes were applied very hard, dealer stated the transmission was replaced. Vehicle has been worked on for water intrusion, carpet had to be replaced, dealer removed and resealed the windshield and repaired the rust in the windshield frame, rust also formed on the mounting brackets under the dash due to water leak, dealer removed and refit the left front fender to gain access to water leakage through the missed body seam and wiring harness. Dealer replaced the fuse box to repair the radio and cluster gauges. Turn signals are inoperable. Consumer states the only repair completed was the replacement of the carpet.
