Wipers quit workin!

[vtx1800sba]

My front wipers quit workin on my 96 2dr. tahoe. The cruise works as well as directional signal. But no wipers or windshield washer. When I twist the arm for mist I can hear a buzzing in the dash but no wiper movement. Any ideas? Help!

It sounds like the motor is still working but the arm that connects to it is probably stripped or disconnected. Not sure how difficult it is to get to the motor on the obs but look under the vent located below the windshield. You might have to open the hood to remove the vent.
Just found this thread, might help you a little-

I am thinking it was a relay. But the buzzing sound is odd. This has happened to me on the tahoe before. I just giggled the directional signal arm around and it worked again. This arm you are talking about, where is it? The wiper arm studs are fine. Know those aren't stripped.

Under the plastic cowl between the roof and windshield you will find all the linkages. If you are suffering from the motor control issue that was from a recall. Let me know And I will shoot you off the info on getting it fixed.

Marc I notice in your profile you did the MPFI upgrade. Was it worth the cost and expense to do it? Any noticeable difference in performance or mpg?

Dealers just replaced the module and here are the instructions on that. if you want just try re-soldering any cold joints you find and reassemble.

Part Number Description Quantity/Vehicle 12463017 Windshield Washer Pulse Control Module 1 (consists of circuit board, cover, and screws) Just about $28 from almost anywhere.

12345739 Goodwrench RTV Silicone Sealant 1 (tube will service 50 vehicles)


Service Procedure 1. Turn the ignition key to the OFF position. 2. Remove the Connector Position Assurance (CPA) and disconnect the wiper motor electrical connector.

3. Remove the three screws that secure the cover to the wiper motor and remove the cover. 4. Inspect for sealant on the inside of the cover and then discard the cover and screws. Important If sealant was found on the old cover, it will be necessary to remove any old sealant from the motor housing in step 6. 5. Carefully remove the module (circuit board) from the wiper motor by lifting up on the end of the module electrical connector. 6. If necessary, remove any old sealant from the wiper motor housing (see step 4). Notice When handling the new module in the next step, be careful not to damage or bend the electrical contacts on the bottom side of the module. 7. Install the module into the wiper motor housing, making sure that the module is fully seated. When fully seated, the edges of the module circuit board will be flush (even) with the motor housing along all sides.

8. Carefully apply a bead of silicone sealant, P/N 12345739 (or GE-162 sealant or equivalent) in the groove of the NEW cover (Figure 2). Remove any excess sealant that is outside of the groove. Important Only apply enough sealant to fill the groove in the cover. 9. Install the new cover on the wiper motor housing and install the three new screws. Tighten
Tighten the screws to 2.6 Nm (23 lb in).
10. Reconnect the wiper motor electrical connector to the wiper motor assembly and install the CPA. 11. Turn the ignition key to the ON position and check the wiper system for proper operation (delay/low/high/etc.). 12. Install the GM Recall Identification Label.

BTW if you have the old spider design just replace it even if it is not a major issue yet as you have the time and funds.

I couldnt tell you about mileage, since at the same time I also did the manifold spacer and ported throttle body.....but for me I did it for peace of mind.

Level of difficulty on MPFI?

V8 Engines
This procedure outlines the steps required to replace the existing Central SFI Fuel System with a new MFI (Multipoint Flexible Injection) Fuel System. Be sure to use the appropriate year and model Service Manual for proper disassembly and re-assembly procedure(s).
1. Remove Upper Intake Manifold plenum and SFI Fuel Meter Body according to Service Manual Procedures. 2. Remove the Fuel Meter Body bracket and discard. Install the new bracket.

3. Position Fuel Tubes of MFI Fuel Meter Body as shown in Figure 3. Fuel tubes 1, 3, 5, and 7 are oriented toward the fuel inlet side of the fuel meter body. Fuel tubes 2, 4, 6, and 8 are oriented toward the fuel pressure regulator side if the fuel meter body. 4. Insert the MFI Fuel Meter Body into the Fuel Meter Body Bracket on the Lower Intake Manifold being careful not to bind the Fuel Tubes. Push down firmly on the fuel meter body until the tabs snap into the bracket locking the fuel meter body in place. 5. Orient the fuel tubes to coincide with their corresponding cylinder. The fuel tubes are numbered on the side of the fuel meter body and the corresponding cylinder number is cast in the intake manifold. Notice :Use caution when inserting injectors into lower intake manifold to be sure the correct injector is being placed into the correct hole. Injectors should not be removed once they have been installed.
Removal of injectors from the intake manifold may cause damage to the retaining lugs on the injector.
Important :The Injector holes are numbered on the Lower Intake Manifold. The injectors are numbered on the side of the Fuel Meter Body. 6. Insert the fuel tubes into their corresponding holes in the intake manifold. Install tubes for cylinders 1, 3, 6 and 8 making sure that the injector electrical connectors are facing in toward the center of the manifold. 7. Insert fuel tubes for cylinders 2, 4, 5, and 7 in the same manner.

Important :When installing fuel tubes, it is important that the tubes are oriented properly to provide minimal interference when installing the upper intake manifold plenum. Intake holes for cylinders 2, 4, 5, and 7 are closer to the fuel meter body. It is necessary to cross tube 5 over tube 7 and tube 4 over tube 2 as shown in Figure 4. Notice :Lack of lubrication will make installation of the Upper Intake Manifold plenum difficult and may cause damage to the 0-ring. 8. Lubricate the Fuel Meter Body Upper Manifold 0-ring (blue in color) with clean engine oil. 9. Inspect Upper Intake Manifold Gasket and replace if necessary. Reinstall the Upper Intake Manifold plenum following the procedures in the Service Manual. Important :Lubricate the Fuel Inlet and Return Lines with clean engine oil before inserting them in the of the Fuel Meter Body. Make sure that Fuel Line Retaining Bracket is properly oriented with the tabs down.
