why is a nonelectronic speedometer needle bouncing
If the speedometer needle is going crazy and not working properly, it is probably the speedometer mechanism that needs to be replaced. It could also mean the vehicle is having a transmission slippage problem if the needle is bouncing back and forth.
Try asking your question again - it makes no sense as presently written. If the vehicle won't start - then it won't run. If it won't run how can the speedometer needle be bouncing? (?????)
If it's an electronic (analog) speedometer needle, you probably have a problem with the dasboard grounding.
The only place you could get just the needle is a salvage yard.
You are not moving!
it's asleep
Send to a speedometer repair shop or replace speedometer head
I didn't know my car was going 72 mph because the speedometer broke. The needle on the speedometer bounced whenever I hit a pothole. The speedometer's needle was stuck at 15mph. Before I could glance at the speedometer, the policeman's radar gun clocked me going over the speed limit.
Sometimes a clicking or grinding Sometimes speedometer needle will fluctuate
Fixing it depends on what the speedometer is doing. Chances are its making a funny noise and the needle is bouncing around. This would be due to a damaged or unlubricated speedometer cable. It is a cable that spins around in a plastic sheath connected to the back or your speedometer and to your transmission. Often times removing it and filling it with graphite powder will solve the problem. If its severely damaged you can replace it with a new one. If the cable isn't the problem you may have to replace the speedometer itself.
Ive had the speedometer needle bouncing off the right peg (140mph) in my stock 1996 Camry one or two times...but as for running flat surface for a mile and a half or so it will maybe do 110-120 or so -Trey
