Thought my problem was needing a new a/c head. Could adjust heat/air temp, but blower stayed on high no matter where knob was set.
Salvage guy replaced with identical unit and no change. He said wasn't ac head, but probably some problem with blower. Is there a relay switch to blower? where? Would love some help. Tired of hearing that blower on continuously!!!! gracias

look it the engine compatment. should be near the right side fender. Not sure what relay is what but it will be there. swap them out until you have a change.

Do you have manual heat controls or the Automatic Temperature Control?
Manual Controls the Blower Motor is controlled by the switch on the dash and the speeds are regulated through a resistor block located on the underside of the HVAC Box close to the Blower Motor.
ATC equipped cars are a little more complicated, all HVAC operation is sent from the head unit to the Body Control Module (BCM), the BCM then controls the Blower Motor speeds by sending a signal to the 14 Speed Blower Motor Power Module which is also located on the underside of the HVAC box close to the Blower Motor.
