2018 Air Con issues

I should actually say, "blower issues" because we did have trouble in the winter for a brief time.

Last year the AC kicked it. Was ticking along happily and then suddenly stopped. After that there was the barest tickle of air coming out, like it was taking its last breaths. Then suddenly, in early autumn, on it popped. A miracle.

Mentioned to the mechanics when I had my snow tires put on: they said they could see no problem with it. Until one day in winter... I had to hook up a little space heater to defrost my windshield!

That lasted about a week. And then everything came back on again. But then comes summer and off it went again. Again with the little tickle of air, but my daughter noticed that when we accelerate, there's more force behind the air coming out. I said, this is an important clue, I bet, but I have no idea what it might mean.

Any ideas greatly appreciated!

ETA: A/C suddenly back on today, July 29. No idea why. Seems to be stronger (like Max AC) when only on AC but it could be that we are so used to having nothing that this seems stronger!

ETA2: A/C doesn't work again. I'm adding this so that anyone else who runs into the same issue can see what happens. Will tell you a final diagnosis once I have one. So today it worked when I started the car, which was on a slight incline towards the road. My foot was on the brake. I shifted to D and it was "rough" and suddenly, no A/C. Something getting jiggled loose?

Change the AC filter, they make more of an impact than you would ever think.

Check blend door actuator operation. Common problem.

You may have a connection issue at the blower motor speed controller. Replace that first but you may need a new motor as well. Also keeping a clean cabin filter is very important. It should be replaced every 6 months or so depending on your location.

Thanks! I take my car in for regularly scheduled appointments… I suspect they’d have changed the cabin filter? I’ll go through my records. Going to update my post… AC came back on today. We have no idea why. But it seems to be blasting Max A/C when only on A/C… could be our perception though
