My ac/heating stopped working last week. I have an 03 S-type w/ NAVI. I can turn it on and change the temp and access the manual controls through the navi but it doesn't blow any air.

I had the air turned up to 90 since it was early in the AM and sometimes it seems to have trouble getting hot unless it's maxed out. ANyway it was on for 3-4 minutes and then just stopped blowing air. I've messed w. it a few times turning it off and on and doing manual control thru NAVI but nothing works. Today it seemed like it had hot air coming out (the temp was still set to 90) but it was trickling out as if the fan wasn't working but some air was escaping due to the fact that I was moving and some air was being forced through. This leads me to believe that the problem is with the fan. ANy ideas? Could it just be a fuse or do you think it's a bigger problem?

Well for starters, check the connection to the fan. Its on the passenger side under the dash in the foot well area. make sure its plugged in and that the connector hasnt melted.

there's no melting down there. it's hard to see/tell but everything seems connected just fine down there. I was driving on a straight residential road when it stopped working so I don't think any wires got jostled when it gave out. Any other ideas?

Have you ever changed out the cabin air filter? That may be severely clogged.

blown fuse/relay maybe?

If your fan isnt blowing at all i would check the fuses/relays next

Thanks for the suggestion. As I don't really know jack about fixing car stuff, where is the fuse box on the 03 tl and which fuse would control the fan?

I checked fuse #3 on the driver door, the fuse for "Heater control, A/C Clutch relay, cooling fan relay" but it was fine. That appears to be the only fuse associated with the climate control fan. What else should I try?
