AC AIR FLOW

2002 Mercury Mountaineer,

Has Very limited air flow, cold ok, just flow amount, is there or are their filters that need servicing ? If so , location please.

It should have a cabin air filter, just google it.

Correction, your out of luck, doesn’t show cabin filter so you probably have a mess on your hands. If it’s low on airflow for fresh air and recirculate then your may have a rats nest in it. Had that happen more than once in the past,

Thanks (I think)

I have a 99 one ton chevy hunting truck that has poor air flow. Had it worked on a bunch. The "baffles" that direct the air flow to various places were all messed up or brittle etc. Mechanic rigged it up every which way he could and helped it some. Put a ton of money into that AC along with my 89 Toyota AC and burned up in both of em this weekend. I just keep throwing good money after bad on my hunting trucks. They did both start this weekend(after charging batt on one.)
edit. Definitely had rats nests in the AC vents before as well.

Know what you mean, its just hard with these older better vehicles (Me included)

Blend door is broke off and laying over the blower intake. Very common on Ford Exploders.

checked the video,,, might be just too much for a 88 yr old, 1 armed guy, considering I didnt even notice it until my Wife was in that car.

Could be a bad blower motor. I've replaced a few of those over the years in various models. Not familiar with accessibility on your vehicle but those I have done are generally not terribly hard to access.

I think this may be your part: Part If you add the trim model in that Amazon link, it will confirm if it works for your vehicle.

If this is what yours looks like, I'd say very easily accessed. Tutorial

I do have a limited amout of air being blown threw the system, could the motor just decrease as it gets older ?

BTW: Thanks for the info supplied,,,VERY helpful

Are you sure the fan is coming on? If not, there should be a fuse to check. If it is turning on low, but not other speeds, it may be toast. I replaced a fan motor in my '99 Frontier. I bought a aftermarket motor on Amazon. That was about 9 years ago, and it still works. Good luck.

It does come on, however very low flow

Absolutely. It can vary from reduced speed to complete failure to blow at all. Works on low but not on high, etc. I've encountered multiple scenarios. I cannot guarantee this is your issue but I can tell you the blower motor was the culprit every time I encountered what you described. Good Luck!

Thanks everyone for the sage advice, think I'll let the proper folks get on it, btw, anyone in the temporary the loan business ? Collateral will be the vehicle.

Aftermarket stereo? They can be too deep and bind up the door controls.
