Hi all,
Starting last month, my speedometer needle will not move and show the car's speed until after I drove it for 10-15 min. Do any member have this problem and how to fix this? Is this a mechanical problem (bad speedo cable) or electrical? Mine is a 93 LS. Thanks for any help.

 

Electrical problem!
No speedo cable!

 

are the lights out too if they are it is the #1 circuit board

 

Well, I forgot to mention that I still have ALL the lights. The needle just will not move until after I drove the car for 10-15 min. Suddenly at this point, it will jump to life and everything is normal again. Sometimes, the tach needle does the samething but not as often as the speedo needle...

 

i have sorta the same problem too.

the speedo wont start up until i hit 20mph.

when it goes back down, it has the same problem.
