I have a 2011 Ford F-150 Lariat and I noticed my rear defrost is not working has anyone ever had that issue?

Yes, many. Take it to the dealer ASAP and try and get it replaced if you have warranty coverage. Very good chance it could lead to the rear window blowing up too. Look of the exploding rear window thread on here for more info. There is a slim chance that it could just be a fuse too.

I have the extended warranty. I didn't see any cracking. It's a windown that slides though is that maybe why? Haven't checked the fuses though

Yep, just had mine replaced over the summer. It must be pretty common, the dealer had one in stock and turned it around same day.

Was it a pretty expensive fix?

Mine was under warranty so I don't know the cost. The rear window alone is over $400

Okay thanks. I have the extended warranty and it's covered bumper to bumper. All I do is pay a $100 deductible. So it's probably worth getting fixed

Mine went out over the summer too. Dealer said there was a bulletin on it. They were backordered for a few weeks at the time. The heated mirrors should still work though.

Pretty sure when it stopped working on my '12 the heated mirrors stopped working too.
I think the slider is what caused mine to fail.

I'd get it fixed for the $100 co-pay.

Mine stopped and was just replaced under extended warranty, the cost is near $1000. Just get it replaced before the window shatters, some dealers make it out to be a glass problem, not covered under warranty. It must be coded as electrical/rear defroster.
