    Cruise control stopped working and speedometer working erratically. It appears speedometer works while accelerator is depressed but when coasting needle bounces all over the place.

Check the Speed Sensor wires on top of the rear differentual just above the connector. The brake cable tends to rub against those wires and can wear through the insulation causing the an improper signal to be sent from the sensor. If this appears to be the problem, I have found other posts that say to get a 2 pin replacement connector ($22) from the dealer and solder new connector in place. Insulate well and zip tie up the brake cable to prevent future problems.

Crusie control doesn't work


The brake light switch (which also controls the cruise control) was not adjusted correctly. Also the stop pad may need to be replaced and the part is available or a penny can be taped or glued in place for a temporary fix.

I have a 1986 Nissan and while i was driving the speedometer just qui working but my other gauges are working just fine


Many times The crusie control won't work either. the seedometer is triggered by a senser on the output shft of the transmission. You didn't say which car or ruck you have or which engine either so I can't tell where the senser is. The wire can come off the senser can wear out and fail the senser can start leaking and the oil can foul the electrical connection. The speedometer can fail too but it's less likly. If it did it may display the chage in miles without showing the speed.

How do I convert my 1979 Trans Am from cruise control to non cruise control? I basically want to remove the cruise and have the speedometer work correctly.


if your trans am is an automatic, there should be 3 levers on your carbuator. 1 would be kickdown cable and run to your tranni. 2 would be throttle and run into your firewall. 3 would be cruise control which would run to the unit on the drivers side inside the engine compartment. Disconnect this lever at the carb and propping it up out of the way will disable crusie and leave you're speedometer functional. If you ever want to hook it back up, it would easly possible this way.
