My damper door pin fell out during a drive

I bought a replacement at Clarks, but I am trying to think what would have pulled it out. There was plenty of tension on the rod springs after following shop manual adjustment instructions.

Hmm, it's possible that it snapped.

Feeble.memory is that there is a metal tab that folded over the head of the pin.

Right, there is a tab that folds over the head of the pin. After several fold/unfolds the tab breaks off. I use a small sheet metal screw and larger washer to substitute for the tab. You must put the screw in a place where it does NOT stop the movement of the damper door.

I have taken a tubing cutter and made a grove around the pin. Then I use an E-ring as a retainer in the pin grove. It holds like the throttle rod on the transmission. Makes for a real clean fix.

I do similar but used a small Dremel disc to make the groove in the rod. I've also seen a cross-drilled hole and a cotter key used.

I got lazy on the last one. When the retaining tab broke I used a strong little Neodymium magnet to hold the pin until I do the E-clip trick.

If you want a stock look and have some of these door panel fasteners you can make a nice clean repair. I posted this repair on this forum March 7 2015 using Clarks LM door fasteners.

I believe these are also available as a Dorman product and other vendors at flaps.


The current part is available from Extreme Amazing part number XA09225525 on Amazon.



The text as follows, sorry photos long gone at photobucket.

These fasteners are the folded metal type and not the white spherical ones.

"I wanted the repair to look factory, without pop rivets or screws and I literally stumbled onto this idea.

The factory tang broke off clean on housing so I drilled two small holes side by side creating a slot at the location of broken tab. These fasteners were from a Clarks door panel kit. These fasteners area also available aftermarket as listed above.

I flattened the triangular section of the clip that normally goes in hole and broke it in half, saving the folded section

Drilled two small hole, side by side, at the location of the broken factory tang on thermostat housing and inserted the bent leg of new fastener at about 45 degree angle and inserted into the drilled two small holes. The folded section holds neatly against the housing.

Finished repair looks like this.
