I am finally going to tackle this project this weekend. I am going to attempt the digitizer screen first,- hoping this is the problem. Her radio controls still work from the steering wheel and nothing lights up and the air is stuck on cool, which now is a problem since the temps have dropped and she needs heat. What I am afraid of is the PC board went like everyone else. $650 seems a bit steep to have it fixed. I am curious as well as to what they actually fixed or replaced. I really hate for her to spend $ especially now that her axles are leaking too.

Your navi unit has similar symptoms to mine.. but then my HVAC cut out entirely after about 2 weeks..... must have known winter was coming and that I couldn't have MAX AC all winter. Anyway, the digitizer didn't do squat, so it must be a bad solder connection on the PCBA.

So I think I am confused on checking the digitizer. Do I check the resistance on the back where the ribbon connects the board? Or do I check the resistance where the ribbon meets the screen? I opened up everything else and the boards seem to be fine.

So I went a few steps further and tested the ribbon from the display it seems to get readings when it's moved im going to contact denso and see if I can order a new ribbon. And hopefully this is the issue before I rip the digitizer apart. Here are few pictures

Did you ever send it out to get fixed? When you checked your digitzer did you not get a resistance? I checked resistance with a few meters, the two I used just had a setting for ohms- where my own multimeter has two settings for 200 or 2000. the two with just ohm settings read no resistance where as mine go a reading when i had it set on 2000 ohms of 446 and 1225 which is still not in the range. I am guessing I should go ahead and attempt the screen fix anyway and see if I can get it work. the only thing that could be lost here is time wise.

I had similar ohms readings when I attempted the DIY circuit writer pen fix. Didn't help my situation.

i tried to contact denso but they never got back to me. I had this feeling it wasn't the screen but the ribbon. How the heck do i reball? And thermal paste? Guess I'll have to google this

Have you done this already? Or do know someone that can? I looked into and this doesn't seem like a job for me. I usually tackle many things but this one I may stay out of.

I am pretty sure I figured it out, so the screen fix of course did not work. But I did a little more research and pretty sure I found the board that is needed to fix this issue.
