Why would GM do this?

I changed my HVAC system in my impala over to the roadmaster auto HVAC. My heat hasn't been working and I figure it was something with the mixer door actuator. I finally looked at it today and look at what I found.

Why the F would GM make that part weak like that? There's no reason I can see as to why they wouldn't make it solid and therefore not possible for this to happen.

One of the two thin pieces broke off and now the actuator can't turn it. This piece would be a PITA to replace. I'm thinking I'll try and try some plastic filler and reshape the part to a solid piece like GM should have done in the first place.

Here's the stock HVAC cable control to show there's no reason to have not made it solid.

It's a 20+ year old car,give GM a break. They could make every piece absolutely bulletproof,but nobody would buy the car when it costs 3-4 times as much to make. I've got the same part in the same car,and mine still works flawlessly. As I'm sure do literally thousands of others....

You're right, my complaint is not legitimate. Sorry I waisted your time reading my post.

LOL Getting a little bunched up there eh. I think you were just getting called on what's gonna hit many as a comparatively weak 'first world problem'. Whatever that part is it may have started out more robust and more than adequate for the job. But the same design likely never got reviewed for carrying more load as all amenities on even the same models ALWAYS get bigger and heavier, often without support parts keeping up. Plus, configuration changes for convenience of installation, lower quality spec material in the constant hunt for 'cheaper', and maybe lack of periodic lube all contribute to eventual failure. Find a 5-year older version of that thing and there may be differences.

And get with it. You're supposed to be buying a new car every 4 years anyway. Word gets back with such low failure rate, especially so far out of warranty, and they'll sick a team of 20 on figuring out how to cheapen it up a bit more.

Off course it's a 1st world problem. ? 90% of people in the US only have 1st world problems. It just seems it would have been easier to cast that part as a solid piece with two flat sides on it. So I guess the answer is, to save money on 1/4 square inches of plastic.
