Honda Ridgeline Climate Control Failure: Blower Problems

Hey there! I've got some experience with car repairs, and this hits close to home. I had a really similar issue with my 2012 Honda CR-V last summer. The symptoms were exactly what you're describing, weak airflow and terrible temperature control. Took it to my regular mechanic who diagnosed a faulty AUC sensor. It was a pretty straightforward fix, they replaced the sensor, and it cost me about 90 Euro. The whole thing took maybe a couple hours, and the climate control's been working perfectly since then. Before you jump to conclusions though, what are the exact symptoms you're getting? Does it change if you adjust fan speeds? And have you noticed any warning lights? Would help to know these details to confirm if it's the same issue I dealt with. Also, quick heads up, I always recommend getting it properly diagnosed rather than just replacing parts. My with a Honda Pilot tried the DIY route and ended up spending more in the long run.

Thanks for sharing your experience! Yeah, the symptoms in my Ridgeline (at 131487 KM) are pretty consistent regardless of fan speed settings. No warning lights showing up, but the airflow is super weak even at max speed, and temperature control is basically non-existent. It's really frustrating, especially during my daily commute. Had my regular maintenance done recently but this issue started right after. I'm thinking of getting it checked by a certified mechanic, just to be on the safe side. The AUC sensor replacement sounds promising and not too expensive. Did your mechanic mention any other potential causes I should look out for?

Hey again! Sorry to hear you're still having trouble with your Ridgeline. You know, after fixing my CR-V's AUC sensor, I actually learned quite a bit more about these issues. While the sensor replacement worked great for me, I've discovered there could be a few other culprits causing similar symptoms. In my case, my mechanic actually pointed out that a clogged cabin air filter can sometimes mimic these symptoms. Have you checked yours since the maintenance? It's a quick and cheap fix if that's the problem. Also, after my repair, I joined some Honda forums and learned that sometimes the blower motor resistor can act up too, especially in models around our years. One thing I noticed with my CR-V before the fix, the air would sometimes smell a bit musty when I first turned it on. Did you notice anything like that? This could help pinpoint if it's really the AUC sensor or something else. Given what you're describing about the timing (right after maintenance), maybe have them check if something got disconnected during the service? My friend is a mechanic and says this happens more often than you'd think. Let us know what you find out! Really curious if your issue turns out to be similar to what I dealt with.

Thanks for all that detailed info! The musty smell part really caught my attention because yes, I've actually noticed that too when starting up the car! And now that you mention it, I can't remember the last time I changed the cabin air filter, might be worth checking that first before diving into the AUC sensor replacement. I just called the maintenance shop, and they agreed to take a look to make sure nothing got disconnected during the service. The tech also mentioned they'd check both the blower motor resistor and the AUC sensor while they're at it. Really hoping it's just something simple like the cabin filter! Thanks again for sharing your CR-V experience, you've definitely helped me narrow down the possible issues. I'll update once I figure out what's actually causing the problem. Fingers crossed it's as straightforward and affordable as your repair was!
