Hi everyone... I have been lurking around this site for months and have enjoyed the information everyone has shared. I have a 05 base crossfire and have loved it since day one. I had it now 3 and a half years.

The latest problem is the AC unit. The AC unit runs perfectly as it should. The problem is when I turn it off either by the switch or if I turn the engine off while it is running. I hear a crackle and clunk. It practically shakes the dashboard. It almost sounds like the blower is slowing down and rattling because it is out of balance. It makes the noise for a couple of seconds and that is it. I think it also makes the noise when I first turn the fan on but it is very faint.

I have a max care extended waranty so it is covered. I just hate bringing it in to the dealership if it is something I can do myself. I read previous posts that leaves and stuff get in the motor. A month ago I did check the cabin filter and found leaves in it. That must mean they went through the blower first. I hate to admit it is still the same cabin filter that came with the car. I never knew it had one until a month ago. I just got a new MB filter and I am going to replace it this weekend. Could this noise be a result of having an old filter? Do you think the fan blower motor is bad? Or do you think there is dirt and leaves in there or something? I only hear the noise when I turn the fan off... not while it is running. Thanks guys!

 

One last thing... I am having trouble getting the new cabin filter in. It seems thicker than the original. Anyone else have that problem? It is the right part number because I checked with 2 dealerships. It should be tight but it will fit, right?

 

It does fit tightly as I recall.

 

When I partially removed the bottom panel that hides the fan motor, there were alot of twigs and leaves and other debris that had to be cleaned out. So change the filter, clean out all the debris and everything should quiet down. Good luck.

 

We heard noises in our air conditioning fan motor so I took it apart and cleaned out the filter AND the fan blade housing. We have a 2006 Crossfire, Roadster Limited

I was pretty sure it was leaves and I think the air intake design is bad cause it lets a lot of leaves get into the AC filter area and on into the fan housing

To remove these leaves you have to remove the glove compartment

And then drop the fan FILTER

When we did this we saw tons of leaves in the filter. The filter drops down after you slide the white plastic holders aside

We also had leaves in the fan housing

Whole job took about 2 hours

 

Great write up and pics. I noticed when i have the AC on and step on the gas i get a whistling noise from the right side of the dash. If i let off it stops. Is this caused by filters clogged/leaves and junk?

 

I had a dead mouse fall out when I checked my cabin filter...

 

I cleaned that area and changed the filter, and cannot see why you have to do that much work. Take out the glove box is not required unless you like work. You can even get at the fan.

 

Yes, it looks like I took way too much apart. And when I put it back the glove box door was not aligned just right so I had to take it all apart again.

Thank you for the input.
