Most likely it is the VSS. Vehicle Speed Sensor. Have it checked out at your local garage or buy a new one and do it yourself. Although a computer check would be preferable first to obtain any codes.
The gears in the speedometer are stripped. If the odometer is working then you have input.
It is quite possible in a 1996 Mercury Cougar, that when the dashboard instruments all quit at once, there is a fuse that has been blown. Most of the gauges in the dash run off the same fuse in most vehicles.
If the speedometer continues to work - probably a broken gear etc. in speedometer head and probably will have to be replaced. If speedometer does not work -- probably a broken speedometer cable
remove dash replace bulb(instrument cluster)
are you sure it is not tail shaft sensor. This would be for your speedometer
Check the speed sensor.
its something ps. i dont know that peps
Check for a blown fuse.
cougar 1989 no lighting in dash instruments or speedometer. Where do I look for an open circuit. Fuses all checked good.
If the gages in a 2000 Mercury Cougar at not working, it is likely that a fuse is blown. While the chance is slim, there could also be a wiring harness malfunction.
The gears inside the odometer broke due to heat and age. You can buy the gears and replace them yourself. Or you can take your car to a place were they work on odometers.
Mercury Cougar was created in 1967.
