Notice

ATTENTION: We are currently averaging a 2 to 3 business day turn-a-round on repairs after we receive your unit. Please retain a copy of your tracking number when shipping your unit in to us for repairs since we do not send out notifications of your packages arrival. Closed Thursday and Friday for the Thanksgiving Holiday  

In most cases an illuminated warning lamp will be on because there is a fault in the system associated with the light.
It is recommended that you have your vehicle scanned for codes to see if there are any present and then have your vehicle troubleshooted and repaired as necessary.

There are some vehicles that may illuminate a warning lamp or multiple warning lamps and the fault is in the cluster.
If there are no fault codes in the system then that may be an indicator of the instrument but can be other things as well.
