Customer Question

maybe, I have a 2010 ford fusion hybrid with dual ac control. The relay that controls the blower motor went bad and I replace it. Now the air flow is very poor, it changes speeds and it blows cold. Any ideas

Yes take a look at the cabin air filter behind the glove box. it pops out easily and is most likely dirty and restricted. Clean it off if it is a screen style or just remove it and see if the airflow is improved and replace as needed.

already tried that, even tried running with it out and same problem.

Ok does the blower motor blow at full speed. You mentioned replacing a relay. If there is no air restriction through the cabin air filter, I would suspect a weak blower motor itself. With it removed it should move fast and push a lot of air, if not, I would suspect a weak blower motor

I have two new blower motors that I bought trouble shooting the relay. They both work the same. Also tried two blower motor resistors, still same issue.

Then if the blower motor is working properly one of the interior blend doors inside the heater/ac box behind the dash is not working properly, restricting the air flow. A diagnostic test for codes of the HVAC module(ac control module) might show a code to point you in the proper direction.

its blowing cold, wouldn't blend door make it blow warm?
Expert:  HDGENE replied 1 year ago.

Only if its a temperature blend door, there are several mode doors inside the heater ac box to direct airflow

Ok there is a Technical service bulletin for reduced airflow but after extended driving and it calls for reprogramming the hvac climate control module. This may be part of your concern, since an update for themodule is available I would start there or at least run a diagnostic on the hvac module which would have to be done at a dealer unfortunatley
