where is turn signal relay located at 1989 mercury sable
In a 1989 Mercury Sable : Both the 3.0 and the 3.8 litre V6 engines have a timing CHAIN
The 1989 Mercury Sable 3.0 liter engine EGR valve is located on the firewall. The valve will be on the passenger side of the firewall.
According to my Chilton's Auto Repair Manual : For a 1989 Mercury Sable : ( 16.0 U.S. gallons , or the optional extended range tank which is 18.6 )
The ground is negative
Speed Sensor is not working
Drivers side on the frame paralle to the tranny , you have to get it from underneath..
The speed sensor is located on the top of your transmission. You can see it pretty easily by just climbing under and looking for it.
The speed sensor on a 1989 Acura Integra is located on the transmission. It is a small unit with a two-wire clip which connects to the main engine harness of the vehicle.
Usually that would be the case, however their are variations in both cars.
check for a faulty speed buffer module
Probably does not have a speed sensor. It would have a speedometer cable that goes from the back of the speedometer, through the firewall, underneath the car, and into the transmission.
