is this the right one?

[soon2bsick]

So I have the same problem alot of people have had, my AC only works at highest setting, ect ect

I know the answer is to replace the AC Blower Relay

and fast parts network has it for $70, However I was looking at rockauto.com and I came upon the tab for "blow motor relay" and they have like 6 and they're all under $10... so... am I just looking at the wrong parts here or what? when I searched under explorer V6 and click the same tab they said particularly "AC BLOWER RELAY" but when I did the same search for my mountaineer v8 in the same tab they just say Blower Relay


The only other thing I saw was AC Compressor Clutch Cut-Out Relay? I didn't think that was it but i don't know

Take a look and see if you can please help me out

Clarification

Do you have the standard HVAC system?
Wouldn't you want to replace the blower motor resistor if you do?

I have the electronic buttons one

I think you need the 4P1529 Module (80.79 ea) or the RU539 Module (70.79 ea) for the auto temp system. The others are for the manual temp control system.
