March 27, 2005ASSUMING the wipers are turned on and off by a switch on the steering column, AND that by saying "or when they do, you put it in park and they come back on", you mean when the vehicle itself is put into park, AND the vehicle is column shifted ....... I'd say the wiring to the switch is at fault. There's probably a cut in the wiring, in such a way, as to cause these problems when the inner part of the column is moved during shifting of the vehicle.
March 27, 2005i have a 1987 chevy and i think you have a problem with the signal switch witch has the wipers and cruze function built in,on mine the wire leads for the cruze flexed enough over the years and they finaly broke.the new assembly can be had from chevy or o'reiley auto parts, about $85.00 to $115.00.
March 28, 2005Thank you for the help, and yes this truck has cruise control, but the cruise still works. Even if the truck hits a bump hard enought it will activate the wipers. I do assume it is the switch, and if thats the case, how do I get to the wiring harness, I know how to get the handle off, just not the harness.

1. Disconnect the negative battery cable.
Remove the steering wheel. Remove the turn signal switch.
2. It may be necessary to loosen the two column mounting nuts and remove the four bracket to mast jacket screws, then separate the bracket from the mast jacket to allow the connector clip on the ignition switch to be pulled out of the column assembly.
3. Disconnect the washer/wiper switch lower connector.
4. Remove the screws attaching the column housing to the mast jacket. Be sure to note the position of the dimmer switch actuator rod for reassembly in the same position. Remove the column housing and switch as an assembly.
Note: Some tilt columns have a removable plastic cover on the column housing. This provides access to the wiper switch without removing the entire column housing.
5. Turn the assembly upside down and use a drift to remove the pivot pin from the washer/wiper switch. Remove the switch.
6. Place the switch into position in the housing, and then install the pivot pin.
7. Position the housing onto the mast jacket and attach by installing the screws. Install the dimmer switch actuator rod in the same position as noted earlier. Check switches operation.
8. Reconnect lower end of switch assembly.
9.Install remaining components in reverse order of removal. Be sure to attach column mounting bracket in original position.
March 30, 2005I'm having a problem with my 89 chevy windshield wipers too if i cut them on they will go the speed i have it set at for a few seconds then the start going faster and once they have picked up speed if you try to cut them off they keep going for a while then just cut off I guess I should just be happy they work. but it is kind of annoying isn't it?
March 31, 2005Big Black Chevy .... Sounds like the switch to me ... Wait, Does your wipers have time delay / intermittant wipers? If it does then the problem may be in either the intermittant module attached to the wiper motor, or the switch itself ......
