Popping Noise Behind Dash After Start

I started my truck this morning (2011) and heard what sounded like a switch behind the dash popping about 5 times. Anyone come across this before? If so, what the hell is it and how hard is it to fix?

Thanks!!!

If your AC is on when this happens at start-up...Take your truck into Ford and have them replace the blend motor. Mine did this for quite some time, and I just had it fixed a couple weeks ago... gotta love the sound of silence!

Ok cool. I make sure my air is turned off before I turn it off but not sure if the wife does when's she drives it. How much did it cost you, or were you still under warranty?

Didn't know if I should try to tackle this myself.

I got mine done under warranty, but I don't think its an expensive fix...just time consuming as you have to disassemble part, if not all of the dash, to get to the motor.

Even if the AC is off, it might do it when you turn it back on after the truck has started....heck, I'm not even sure if the AC is required for the "pop" to happen. It might just be a fan function. Also, depending on your settings, remote starting the truck can turn the AC on.

Thanks. I'll get it in the dealership to get it fixed.

Spoke to the service guy...he said there are two (an upper and lower) one. The lower one can be changed without removing the dash while the upper one cannot. Price is about $250 for lower and $700 for the upper. He also said that these are common failures and covered by warranties.

Just an FYI for anyone who didn't know.

Will tell you this on the "door" issue if mine starts popping again after replacing it once already I will just go trade it in. The Raptor is a nice truck but it does have issues.

I have done a Driveshaft, Moon Roof, wiring harness issue plug, blending door issue, seat heater dead, drivers side window switches, still have the worst AC in any truck I have ever had. Have 61k on the Raptor now which is not a primary driver any longer replaced by the Jeep. I just need another year till the new Ford or maybe go back to Chevy.

I might have this issue, but I can't tell if it's a popping or more of a vibrating sound.

No if you have what I did it sounded like an evil Gremlin in the dash with a tiny hammer whacking on the plastic.

Gotcha. Mine seems like more of a metal vibration that goes away after about 3 seconds after start up. Thanks BH.
