The speedometer on my 2002 Mercury Cougar is acting up. Sometimes it will work but its rare. Whenever it does work, it will kick on at about 45-55mph. However whenever I push the clutch or hit the bra

If it is a speed sensor(only one on the transmission) then it would set a code. Since it is intermittent, the light might not come on. But it would be in the history codes. My guess is the speed motor in the cluster has a bad solder joint. If it were the logic chip, all the gauges would act up or just not work. You can also have the instrument panel scnnaed for codes.

My 98 mercury mystique is missing 3rd gear it goes 1st and 2nd fine but wont go over 30mph and no matter how high the rpm go it wont turn over into 3rd gear Help

The likely problem is the VSS or vehicle speed sensor. The transmission uses the speed from the speed sensor to determine the shift points. You should have the check engine light on it will probably show a code for the speed sensor. Hope this helps!

My speedometer bounces when i hit 45 miles an hour, what do i need to do?


Problem is usually the speed sender failing when speed gets too high. In some case the speed gauge itself is damaged. In Mercury the speed sender is located in the transmission. The part is difficult to test without professional equipment. Repair is done replacing the speed sender. If that does not fix the problem, work on the instrument panel speedo.

Here location of the speed sender:

Heater fan on 1997 Mercury Mystique only works on "high" after replacing blown fuse.

You will need to replace your speed sensor switch located beside blower motor 2inch by 1inch single plug if you had a replacement in hand you could better identify it.
