2005 chevy trailblazer radio speakers work sporadically and now the speedometer is reading 40 mph in town and 80 on the highway when going 50 to 60.

check engine light is on, showing code for the cooling fan, which has been replaced in 09 and seems to work fine, no overheating problems.

It didn't set the code because it's working fine.

There is a known problem with these chafing through the cooling fan harness inside the fan housing and the harness has to be replaced.
