1994 Nissan KingCab automatic the OBD lights comes on inermittently, the tachometer is stuck, the odometer works intermittently - have less than 100K miles, the passenger lockset don't work, = Where can I go to purchase replacement parts for the above issues. > tanx for the help > mahalo - aloha - lgb

If you bought it from a car yard,take it back to get repairs.The speedo fault may be from the speed sensor head on the gearbox which will in turn set off the OBD light.It seemed to be a common problem in that year for the tacho fault.Both speedo and tacho fault can be in the instrument panel.So it may need to be tested anyway before replacing parts and wasting $$.Try squirting some powdered graphite into the lock and rattling the key and pushing it in and out.Locks that aren't used much can freeze up.You can use WD-40 but graphite lasts longer.and is preferable for all locks.
I Cant help you with specific places to go due to different country but try car dismantlers or google for places in your area.Most states,cities have there business phone books online also.
I hope this helps you with the problems and minimises your spending.

Firstly check with car scanner first than talking changing
