Do I need any mounting hardware to install this?

Assembly mounts at factory blend door locations — hardware requirements depend on your truck's specific dashboard setup. Check your HVAC housing before ordering to confirm fastener type and count.

Will this fix my A/C not switching to recirculation mode?

If your blend door is stuck or broken, replacing it restores both recirculation and heater blend function. Verify the door itself is the fault (not a control actuator or electrical issue) before committing.

What's your return policy if this doesn't fit?

Review the fitment details on your specific truck's model year before checkout. Contact support with photos and your VIN if installation reveals any incompatibility — they'll work with you on next steps.
