It fixed 2 problems--AC going off and on (breen light too). Ac was always pulling outside air in--now I can switch to recirculation. My husband had no trouble with the install even tho he is disabled.

Removing the OEM seals were harder than I expected. However, installing these new ones were WAY easier than I expected! The new clips lined up perfectly, even though I didn't hear all of the clicks. They are firmly in place and look great.
The quality and fitment was on par with OEM. It was an easy install with no issues.
