How do I replace the cruise control lever? by oldtexasglory

I have a 1991 Chevy S10 and I am replacing the cruise control / turn signal / wiper lever. I have pulled the steering wheel and the turn signal plastic switch. I cannot seem to locate what holds the lever in place. Anyone have experience here that would help??
 
Thanks

I have a 98 S10 with the same problem. When the wipers quit I wiggle the electrical plug from the wiring harness where it plugs into the wiper motor & the wipers usually work fine for awhile. I checked & cleaned the electrical connections but there doesn't seem to be anything wrong. I took the cover off the wiper motor & found a printed circuit board. The printed circuit board slides out of the motor. On the back side of the printed cicuit board is 2 electrical contacts that slide on metal strips on the main gear of the wiper motor. Carefully clean the contacts & the metal strips on the gear and reassemble the wiper motor. I found that my contacts & metal strips where covered with grease from the gears. This solved my problem for awhile but recently the wipers have been acting up again. I haven't had time to check the contacts or printed circuit board again but would assume there is more grease on the contacts. Hope this helps.

96' S10 Headlight short by rostant

My 96' S10 headlights go out often when I driving on down the road. When they go off I hear a click click click coming from the glove box area. Daylight Driving lights are Ok, however the headlights are not functioning all the time. It's a problem because people think I'm flashing my lights at them. Any ideas on what it could be?

The circuit boards on the wiper motor is usually the culprit on s-10's. the board under the cover on the wiper motor. Take it out...look for the BIG solder joints and reheat. That should solve the problem. Or you can buy a new board at auto zone or somewhere for a small fee.

No I did not. Headlights now do not work at all.
Driving lights are fine however, when I switch on the headlights I lose everything. Any help would be greatly appreciated.

I'm working to fix a 1999 s10 with a headlite problem. By looking at the circuit diagrams in a Haynes manual 24071. here is an explaination.
 
When you turn on the ignition key the Daytime Running Light (DRL) Relay back feeds power to the headlamps in series. This means that the power is fed backwards into the left side head lamp "ground" circuit and power flows through the left head lamps into the Right side head lamps to ground. When you turn on the head lite switch it provides power to the DRL module that turns off the running light function. This power line feeds the Head lite dimmer switch to direct power to either the high or low beams.
 
Your description would seem to indicate that the DRL Module and Headlight switch may be working but power is not getting to or through the dimmer switch.

92 S10 Blazer digital dash problem. I have good power at connector, good ground, speedo and trip light up, ses and other bulb powered things work. NO fuel, temp, oil, or volt indications. Checked refreence volt out of PCM which was good. Is there a pull up relay or what to provide a resistive load to the LCD displays?
