The Heater/AirCon Fan control module has failed and my local dealer here in the UK has quoted $300 !

On Amazon I can see modules for much less - around $50 shipped to the UK

My problem is I do not know which aftermarket unit I need, there are so many to choose from.

My vehicle serial number is 3GNEK12T14G327268

Any help would be appreciated.

Thanks Dave.
 
AFAIK, the fans in the Avalanche are run directly from the main HVAC controller (the one with the buttons and knobs on it).  That would be the $300 part.  I paid $150 for mine to fix a recirculation door problem.  Would never be $50.
 
What is issue?

There is a blower resistor module to give you the various fan speeds
 
I need to replace the blower resistor module fitted above the front passengers feet.

The unit I have taken off has a two wire lead and a 3 pin plug.

Thanks Dave.

Mine is automatic temp, dual zone
 
Rock AUto is your friend and may ship to UK?

Options are:

They show 2 versions so compare to what you take out of yours.

Also your old one might have PN on it.
