Having problems with your 2004 Chevrolet TrailBlazer ?

What is a fan speed high code 0495 on a 2002 trail blazer

Posted / edited by AnonymousUser on : 19-02-2018

Answers :

The cooling fan on the engine has sensor that might mean that the fan is going faster than normal. Try resetting the main computer by disconnecting the car battery for about 35 seconds. Reconnect the battery. If the code comes back, there may be a problem with the fan. Try replacing it. Remember that when you disconnect the battery, you will loose settings on the clock and radio. Hope this works for you.
