A/C Blower dead

Hello all,

Sorry if its a repeated post, I'm new on here.
While cleaning around the head unit of my 2011, 3.7 V6 Mazda6, some fluid may have gotten into the A/C's switches; (A/C, Mode, Air Circulation...) and now, the backlight of this section's switches is off, the center display still shows the different A/C functions being selected but the blower is completely dead and compressor doesn't react to the "A/C" on/off switch.

Checked all mini/micro fuses inside and under the hood, all seems to be intact.

Where should I start looking to determine what went wrong/fix the problem, please?

Any input would be greatly appreciated

Check the relays? ac and blower relays should be #6 and #8 in engine bay fuse compartment.

You can test it with a multimeter. It's a generic part.
