What is your question?
Took my Tahoe to Auto Zone to have it scanned for a problem with fan blower but scanner could not read from port under driverside dash, apparently scanner could not read anything ?

whats your blower doing? is it not working? no heat? variable speeds not working? or only some? need more info to be able to help with the port, you may have to contact a deal and have it replaced to so it can pull the codes proplerly
