Speedo works only at 55 or more

its a super old car 1990s" or older with cable drive speedo
and most have the actual speedo bad.(guts)
I fixed losts in year 2000. using 2 used speedos and swapped guts to get one good one.
yes I dead 1997 sidekick, G16b. the speedo has needle and shaft and a spring and bushing
the silly bushing wears out, and the needles goes nuts.
the needle is magnetically coupled,
seen here, (mine)

I have shared this with many sidekick owners world wide.
there is no fix.for bushing, (hacks maybe)
there are no spares sold by maker here.(out of stock forever)
only buy used speedo cluster off fleabay ,works
warning there are 15+ speedos, most will not work (2door and 4 not the same, and county) just in North America. more world wide.
the transmission has different gearing and axles change this tool.
secret, speed P/N pulled out, cluster, bottom has the real part number.>> look here.
USA or canada, KPH or MPH. versions.

that\'s a good one but id do this.

1: kill the whole HVAC system power, (FUSE pulls) under stand how.

if this is not clear, ask or read the FSM page on HVAC.

it might be a berserk damper motor (device)

this car is TJ

using 2 persons to find noise works best and at 55 that big time danger. no? so do that, one drives. other uses a rubber hose to his

ear to find LOCATION, like in real estate, location is every thing, LOL.

its not a bad speedo cable, there is no such ani-mule on this car.

electronic end to end.



before working on any car, 96\' to now, defeat the air bags per FSM

first or get broken neck or worse at 55mph. really... RTM.

DO not ever work on cars with no FSM or find your self, playing harp.



I put my bet on HVAC

and using a real scan tool not autozoned junk, and see if you

have HVAC DTC errors.

i use a Innova 3160 and it shows them all. (so do others)

the $29 code readers are pure junk, on newer cars.

ok on 1996, but not newer cars with CAN buss or advanced electronics like ours.



SCAN IT FIRSTS ! THEN ASK QUESTIONS.

fooling around air bags at 55mph is fool hardy.

I would suspect you have a faulty electronic speedo head, have the cluster removed and have it sent out for repair of the problem. There is no at home repair procedure for this problem, it takes special equip to repair the speedo.

The speedometer sensors on these cars can go bad sometimes and often, and also low power steering fluid can effect their readings. Check your power steering fluid level and see if that is the cause, If not, the sensor is probably worn out a bit.

i would try a speed sensor that would be the signal for both speedo and odonometer

Im having trouble as well with shifting higher than second gear and me speedo doesn't work.checked all fuses replaced vss (both) and still no speedo or shifting. any ides would be great. I have power at buffer and tranny

A reliable fix would be to send the cluster out for repair, if in fact the problem lies in the speedo head. There is a bulletin for this car that states that at 20mph the speedo can be + or - 4 mph inaccurate, and its normal operation.
I suggest first having the alternator tested. The VSS on this car produces an AC voltage signal. The alternator also produces AC voltage, which is converted to DC before it is output to the cars electrical system. If any AC voltage is leaking from the alternator, it can interfere with the VSS signal, and cause the speedo to read higher, or even show that the car is moving when sitting still.

A vehicle speed sensor that is starting to fail could cause this, or less than likely bad wiring or connections, or yes, a bad cluster could do this... But how exactly did she notice the speedometer was 10MPH fast?? There are no real accurate speedometers in vehicles (Don't get me wrong they shouldn't be off by 10MPH) but there is a 5 or so percent difference high or low in many vehicles even with stock powertrains. I've plugged in with a diagnostic scanner on many vehicles and the dash speedo shows 60MPH, but the electronic speed readout on the scanner reads as low as 55MPH or as high as 65MPH

The speedo head or cluster is the part that houses the speedometer and tach, etc. now it may be the speedo cable that comes from the transmission to the speedo head that has broken. If so replace the cable and your back in business. If it is the head you can get them from your local recycle yard.

There are 2 speed sensors on the transaxle. One is for vehicle speed and one is for trans output shaft speed. My guess is that you replaced the one for output shaft speed.
