So to start – I’m… capable, but inexperienced, as it comes to cars? I can understand directions, just don’t know a lot on my own.
Backstory, in case anything is relevant - in my 2002 Highlander, the top cluster of my center console controls (clock, hazard lights, passenger seatbelt warning, cycle air button, A/C button, rear defrost) have not been working for about two and a half weeks. It’s been on my radar, but I hadn’t had time to take it in yet. Drove fine, A/C worked, all of that – mostly just the clock was an inconvenience.
Two weekends ago, my battery died. Took it in, Advance checked it out and topped off the fluids, cleaned corrosion and sent me on my way – said the corrosion might just be shorting it out (it was bad), but that while the battery was old (4.5yrs) it might still be fine, so to try that and come back in 100 miles or so before buying a new battery.
Worked fine that week, died this past Saturday. Went in to get a replacement battery, had it put in, all good. Chugged a little on the first start after the battery was installed, had them check the starter/alternator, they were fine. Started normal after the first time.
Went to leave, and noticed my air conditioning was now coming out of the defrost, instead of the forward setting I left it on. Long story short, now that dial doesn’t work, and I can’t change the airflow direction. (Advance aren’t techs, he had guesses but no ideas for sure – something with the battery resetting the switch to the default).
The temperature control still seems to work – it doesn’t get quite as cold as it did (not sure if that’s a new issue as well, or just how the defrost portion works). I can also still change the strength of the air blowing out – basically, the other two A/C controls work, I just can’t change WHERE it’s blowing out.
My guess was that it would be fuse-related, but I checked all the fuses that I could tell from the manual might have something to do with the A/C (or the center console controls I mentioned), and none looked blown/broken.
I’m not really sure what else to look at – my wife’s dad might be able to help, but he’s busy often, and we’re going out of town on Sunday. Any ideas what I could look for? Appreciate any help.
