Does anyone know if there is a fan or compressor in the right (passenger side) part of the engine compartment?<br>When I turn on the aircon something starts turning and vibrating like crazy, the whole car shudders.<p>Could this have anything to do with the timing belt? Just to be safe I'll drive without aircon untill I can get to a dealer.

Re: Aircon vibration (Sjappi)

Most likely not as issue with the timing belt, however sounds like an issue with the serpetine accessory belt, or something it drives, like the A/C compressor, idler, alternator, etc.

Re: Aircon vibration (rogersampson)

My A/C always adds a lot of vibration when it cycles on and off. It's not crazy, but it's pretty noticable. <p>I always thought that this was pretty common...

It's not when it's cycling on and off. As soon as I turn the fan on the whole car starts shaking like something unbalanced is turning around.. It's the whole time not just when it kicks in.

No vibration from my fan or AC at any setting... switching the the AC on/off is imperceptible save for the change in air temp.

I still get the vibrations when the engine is turned off and when the a/c is turned off. So I'm guessing it's just the fan that needs replacing. Will post again when I visit the dealer.

This is most likely a defective relay, or faulty temperature sensing.

When I put it to max the whole car starts shuddering (nog engine running). It's definately not the fan in the front.

Re: (Sjappi)

OK, it has to be your HVAC fan. It is on the right side, in the dash.<p>I don't know how handy you are but if you remove the outside cowl, you will see the fan blade. It could be that something is in there or it could be that the fan blade has thrown off a balance weight.<p><IMG SRC="http://i620.photobucket.com/albums/tt290/justsam/IMG_2798_edited-1.jpg?t=1243888534" BORDER="0"><p><br><IMG SRC="http://i620.photobucket.com/albums/tt290/justsam/CIMG0827_edited-1.jpg?t=1243888461" BORDER="0">

What a bitch to get that thing out. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0"><br>There was some rubber strip stuck in the blades unbalancing the motor. Removed it and everything seems ok again. I think the rubber strip was the seal between the white in your pictures and the blades so I think it's not blowing as hard as before. Will have to check if they sell that seal seperate.

Oh and a little how to:<p>Remove the plastic strip that sits in the door<br>Remove the plastic strip in the middle console (use a coin to turn the clip)<br>Remove the piece that sits under the glove box<br>Pull back the carpet towards the seat<br>Unplug the blower motor wires<br>Remove the glove box<br>Unscrew the 4 or 5 torx screws from the blower motor.<br>The motor will fall out.

Re: (Sjappi)

Excellent, you came at it from the bottom as opposed to the top at the cowl. <p>Believe it or not, this is a fairly easy blower removal compared to some older Volvos, where it felt like they started building a car by setting down the blower, and then built a car around it!

Re: Aircon vibration (Sjappi)

Wow, what an amazing coincidence--my 2004 just started this yesterday! It scared the crap out of me when it started, I thought I lost a serpentine belt or something.<p>It's 100% the climate fan, the vibration goes away with 0 fan, shakes the entire dashboard at full, doesn't matter if the AC is on or off, or even if the engine is running. I called the local dealer an they thought something had been sucked into the fan, I thought it sounded like the impeller had lost a blade.<p>I'll pull the motor and see what's stuck in there. At full speed fan, the dashboard vibrates so bad, it's incredibly insettling.

Re: (rogersampson)

OK, thank you rogersampson for the clear instructions. I didn't even need any tools to pop the plastic rivets out, pull up the cowling, open the trap door and.....pull out the long ribber gasket that was sucked into the fan! I recently had my windsheild replaced, and in addition to not reconnecting the rain sensor and breaking almost all the plastic trim clips, the idiots also didn't clean up after themselves very well. Somehow, Sat. afternoon, a foot long chunk of old gasket was pulled in and blammo!<p>Now if only I could get someone to pay me $150 for the hour of labor this took, thankfully I didn't have to pay Volvo for it.
