Turn Signal Flasher Unit Problems of Toyota Corolla

I have replaced numerous bulbs to finally be told it's the casing or bulb holder that's defective and they have noticed several problems with rear lighting in this model Corolla. Dt.

See all problems of the 1996 Toyota Corolla 🔎.

Rear right blinker bulb burned out at least four or more times since car was purchased. Dealer found poor grounding first time and after that dealer only replaced bulb, with no further investigation of problem. Trying to get repaired "again". Dealer implies that there not sure if this is a "warranty problem" and I may not be entitled to a rental car. This is only the fouth time for repair, what constitues a warranty problem and accident and several lives taken away. This is a safety hazard, especially driving on the highway at speeds of 70 miles and hour - no one is looking for hand signals. Had electrical failure trying to unluck doors using lock/unlock button while sitting inside. Had to manually unlock door or put key into ignition to unlock doors. Dealer stated problem would not repeat itself, so it was not a problem. Not electrical diagnostic ran. Have noise coming from font end of car. The first time repaired I was told it was some type of "arm" that lost a bolt. Noise ceased for about a month. However, noise did return and grows increasingly louder while making sharp turns, backing up, and on inclines backing up. Sounds as though front end axle is falling off. I was told this is a "normal sound" the brakes make while shifting and it is the sound of all brakes on the 1996 Toyota, Corolla. Sound were not there when car was purchased nor does it state that sound should occur in owner's manual. I feel unsafe in my car for me and family.
