What is wrong with my 1991 Camry power window?
The problem is very common w/ this particular model. The widows utilize a system called the HPWMAS- that is, the Hydralic Power Window Modulated Assist System. Generally when it malfunctions, it malfunctions due to seapage of the hydralic window lift fluid. On these toyotas, the leak is usually right where the hydralic hose connects to the window motor assembly. The preferred method of repair is to replace the hydralic coupling, however, I have used JB WELB and have been successful. Good Luck!
