The wiper blades on my 1990 mazda rx7 will not turn on. can you help

After doing little_t58 checks turn the wipers on and give the moter a tap with a hammer and see if the wipers start if so get a new moter.

also check your wiper stalk on the stearing wheel dose it fell loss and worn out this is not uncommon if so that also may be the fault

First check that the nut on the arm is secute,and that the motor is running ,also check the fues ,if you cannot heare the moter and the fues is ok change the moter
