2008 Mariner Premier Blower Fan

Hello everyone, this is my first time owning a Ford and the first time on the forums.

I purchased a 2008 Mercury Mariner 4WD Premier 3.0 V6 that has the automatic climate and passenger heating control.

The problem I have is that when the system is on manual and you turn the blower fan up it shows that it is going up on the display but there is no increase in pressure from the vents. Almost sounds as though the fan isn't coming on at all.

I checked the 40A cartridge fuse under the hood as well as swapped out the blower relay with one that is marked as not used.

I have not officially tested the relay and I also read in the owners manual that there is a climate control fuse on the inside that I haven't checked.

Assuming those are good does anyone know what to proceed with next to troubleshoot? The blower motor itself could be bad but that seems unlikely to me, is there a way to test the computer that runs the climate control system?

Thanks for any advice.

Jeremie

Could also check cabin filter which can restrict air flow .

Unless that was added by an owner, it's not installed at the factory.

I once saw a long list by different manufacturers that fit but don't remember if it was by certain year. I've never installed one in mine. All I know is that they don't come with one.

@CatSkinner,

I don't believe automatic does anything either, my wife adjusted the temperature to be 90 degrees and it didn't get any warmer inside. On manual systems there is a resistor but am I correct that on the automatic system in place of the resistor is a blower control module?

I believe I can get to both the module and the blower motor from under the glove box with a multimeter to asses whether current is getting to the motor or not. I figured before I did all that I would open up the communication lines with ideas for testing.

Thanks!

Re: 2008 Mariner Premier Blower Fan

You're correct, the blower control module replaces the resistor module, but high is still a full 12V but grounded through the control module. You may have lost that ground. The connection to the motor should be yellow green and yellow blue (Y-G and Y-Bu), Y-G is hot and Y-Bu is ground. See if your getting 12V off of the Y-G when it's supposed to be running and verify you're getting a ground on Y-Bu when in manual high.
