So about two weeks ago I accidentally ran over a divider in a parking lot (had to be less than 5 mph since the divider was right in front of me when I was parked). Everything seemed fine after I just reversed off of it. Then about a week later it rained really bad and I drove through a puddle almost halfway as high as the car. The next day or two days later when I pressed my climate button I get the message, “check connection to air conditioner” and the climate buttons on the steering wheel don’t work either. I’ve actually never used those so I’m not sure if they ever worked in the first place but the climate button worked. I’ve read on threads here that I should get a 68ohm resistor or two 30ohm resistors but I don’t want to go through disassembly to find out that’s not even the issue. Just wondering why he climate button AND the buttons on the steering wheel would stop working. It’s been 95 degrees for the past three days and I just got this car less than a month ago so I’m just upset.
I might be looking for something low in the front of the car that could have been affected by the parking lot divider ... the connection to the A/C compressor, for example. There isn't anything that happens to a Prius that causes the climate buttons to need a 68Ω resistor when they didn't from the factory. That would be more of an interfacing-stock-controls-to-aftermarket-components kind of thing, not something that "just happens" to the car. -Chap
Busola. Just as @ChapmanF has said, could be as a result of the first incident at the parking lot. Is there any display on the MFD showing check hybrid system? You may have gotten lots of flood water into the HV compressor connector.
Hi Chap! Do you know how much labor and parts usually are for something like this? I’m literally not tryna spend more than $1000, if that. Ugh
Would you also happen to know what’s parts I’d need and where I can find the cheapest but GOOD parts? Even refurbished. The issue being the ac compressor makes sense since the rest of the MFD display still functions properly and this happened right after rain.
All those diagnostic screens you show on the MFD are just for diagnosing problems with the audio, nav, and MFD itself. They don't tell you anything about the rest of the car. In general, the way to get diagnostic codes for the rest of the car is with a diagnostic reader plugged into the OBD-II port. As it happens, if there are any HVAC codes, you can get two-digit abbreviated versions of those by turning the car ON while you hold down the AUTO and RECIRC buttons. Any two-digit trouble codes will appear up in the corner of the MFD. Estimating the cost really has to wait until there's more of an idea what the trouble is. Some issues don't need any parts at all, just, for example, fixing up a wiring harness where it scraped on a parking divider. I'm still only speculating. The auto+recirc codes are easy to get, if there are any, so it's worth starting there. Then I would probably just drop the plastic covers under the engine and compressor and get a good look around. You did have a message saying to "check the connection", right? -Chap
