The wipers on my 69 Firebird are very slow on low and not much faster on hi. I replaced the motor with a rebuilt from Autozone (not recommended)and it made no difference. I've had this car for 13 years and they have always been this way. Has any one else experienced this problem?

Sounds like a bad ground. Make sure the ground behind the switch is clean. Is anything else acting strange?
 My Rig's a little old, but that don't mean she's slow.

You sure theres anything wrong? I know the old units are nowhere near as fast as anything newer. Just wondering if thats your basis for comparison? If not then I would definately check grounds on the switch, check the connectors in the plugs at both ends(switch and motor)and make sure the ground strap on the motor going to the mounting stud is good and has a good clean ground connection.
 GR-RRR!

Check your wiper motor mounting grommets. I believe the wiper motor is electrically isolated from the firewall (The motor cannot touch the firewall or any other ground).
Try this: Remove the wiper motor mounting bolts (3). Pull the motor slightly away from the firewall so no metal is touching any other metal. Hold it firmly. Have someone else turn on the wipers. Try low and high. If they work, you need new grommets.

Thats actually not the case, the motor is grounded by one of these mounts. A strap goes to one of them and this is why you basically can only remove 2 of the 3 bushings from the motor. I think the grommets are just to cushion the motor from firewall kind of like motor mounts, they allow some flex for a motor with torque. At least thats what I think its for, But I do know it is self grounded thru one of them.
GR-RRR!

try lubricating all of the pivot points in the linkage.
penray makes a product called inner slide lube that works well on things like that. DON'T GET IT ON THE PAINT! IT STAINS. mike

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
