Just got back from a roundtrip to Memphis with my LR3. On the way back today, I noticed that after about 5-6 hours of solid driving with the AC on and recirc on, it didn't feel like there was the normal volume of air coming out. I turned off recirc (for the rest of the trip), and then turned the AC off for about 5 mins and then stopped for gas. It was perfect after that, lots of water was dripping out. Then again just as I neared home (about 5-6 hours later) it started feeling a bit clogged again. Temps where in the 80s most of the way and then in the 60s once I got back into Wisconsin. Is this normal? It was about 12 hours of continuous driving, with maybe 3 10 minute breaks to get gas. Never have driven that continuously before. AC still blew cold, as cold as ever. Seemed fine on the way there last week. Don't think it's low on charge. FWIW, it's never had AC work done and I've never swapped the cabin air filter. Is this something to worry about?
Thanks!
