Hello,
I've searched the internets, this, and many other forums and it's still unclear what is going on with my Mazda 5 2008.
Recently I've been working on wiring additional devices behind the glove compartment.
By the time I was almost finished, I had noticed that the AC core, - two aluminum pipes behind the leg trim panel (the one that you take off when changing the cabin air filter) are overheating, a lot. In fact, they are overheating so much that I think I start smelling some burnt plastic, which is not normal.
I have another Mazda 5 from 2014, which is perfectly fine and I'm it using as a reference model. It's not overheating as much.
Symptoms I've noticed so far:
- There's a quiet intermittent squealing noise from the right side of the vehicle. It was there for a while, and I'm sure it's not a belt.
- Both cold/hot and intake/recycle actuators are working as expected, it's not a hot/cold actuator getting stuck
- I can hear the click and noise of the clutch being engaged, I don't think the clutch is going bad, but perhaps, it is?
- New fresh clean cabin air filter is installed, but the problem is still here
- Airflow resistor is ok (the one right next to the cabin air filter) - I've swapped it with another Mazda5 and it works in the reference car just fine and vice versa.
- When I remove the plastic screw-on cap on the high pressure / low pressure intake, I hear a single short "psst", which means the system is not empty, there's some pressure. This "leak" is "normal", I guess.
- No error codes
- The pipes are only overheating with AC on
So, my only hope is that the AC needs to be serviced / oiled / refilled, perhaps?
Maybe it's clogged?
Any other ideas on what is going on?
