Thanks for your help.

If your talking about just the blend door part – then that is available at the dealer. The entire case does not need to be changed just the small section that has the doors built in, just like the picture shows – the door assembly.

Great post btw.

I have a broken blend door caused by the corrosion from lingering antifreeze from a broken heater core. The thing just fell apart when I finally got it out.

Now I’m hunting down a replacement. Were you able to find this aftermarket or through a part shop like O’Reily or did you need to go to Mopar/Jeep to get it? I called Jeep and the guy is telling me I may need to replace the HVAC housing… That seems bogus. The guy at O’Reily is trying to see if he can even get the blend door part.

Any ideas since you’ve done it a few times?

thanks

So others know, the article you’re talking about is on another website that I write for occasionally. The job pays about 7 hours (multiply this times the shop labor rate). The cost of the parts will vary depending on if the parts are original equipment or aftermarket.

Since August of 2008 ( 5 months ago) the noise was only moderate, if it hasn’t gotten noticeably louder you may be able to postpone the repair. However, metal circulating in the oil will continue to cause wear and could cause damage to the ring and pinion gears, which are much more expensive than just bearings, races and seals. Since you say it does whine on acceleration, I would think the ring and pinion is worn already -but that’s not surprising on a Jeep, especially one with 170,000 miles.
