Dashboard lights in 2007 Prius Not Working

The "warranty enhancement" you refer to is actually still in effect for some. It's good for nine years from in-service date. Some '09 models are affected, so they'll be covered until 2018 at least. I got my '07 replaced last January.

Look on eBay and you'll see CM repair options for around $100, but you'll have to supply the labor. It's a several hour job the first time you do it, less than an hour the second time.

I've never heard of the CM problem being linked to a low 12V battery, but it could be. It's usually affected by cold temps.

 

Mine is an '06. My lights go out now and then too, but the weather doesn't seem to matter. At those times, the car won't shut down normally; I have to depress the brake and hold the start button down until I hear the fan stop. When it happens, it's like being in a time warp: no mph, no miles period. It didn't begin until after the cut-off date for the warranty, so the dealer would charge me about $1000 to fix it. I'm debating it. After all, it still drives reliably well. (Except now the air conditioning isn't working right. Sigh.)

 

This worked for me. Just wanted to share.

 

PriusGuyfrom213: thank you for that. I just bought a new battery and after watching that video, I probably didn't need to. Oh well, I'm going to keep the battery anyway.

 

Help i have a 2004 Toyota Prius .3 months ago i had the Hybrid battery rebuilt , then i had to replace the Hybrid synergy mechanical pump now my car wont even go into Ignition mode to start help

 

i would test the 12v and connections.

 

The dash lights come on but the Odometer light , the car will not engauge the Ignition system ,. I took the 12 volt deep cycle batttery into Napa had them load test batter was fine . the Hybrid battery was rebuilt .3 months ago , 2 weeks ago i replaced the
Hybrid mechanical pump for the Synergy system since then the car will not go into Ignition mode and start i have tried to do the battery thing 12 volt , and i disonnected the Hybrid battery . i have tried the Gas pedal code and reset , still Nothing , i have checked about 80% of the fuses most look good

 

All i know is when i pull a certain fuse the engine fan comes on but
the parking and the check engine lights are flashing . still no ignition no
speed ometer

 

I don't know what a "hybrid mechanical pump" is.

- There is a mechanical engine coolant pump which is turned by the serpentine drive belt.
- There is an electric inverter coolant pump located by the driver's headlight assembly.

What are you talking about?

Further, I don't understand your comment about checking 80% of the fuses and "most look good". If you are going to check the fuses, every one must be good, not just look good. Use an ohmmeter to verify continuity of each fuse. In particular, check the 10A GAUGE, 7.5A IGN, 15A AM2, and 15A DOME fuses.

If you really want to resolve this electrical problem, you need to substantially "improve your game", so to speak. Good luck.

 

There a quick temp fix with car on pull out fuses on 4 left side under hood then install turn off should work agian. But the real fix is to replace the cap on the display pcb there 4 of them.

I bought my '07 Prius brand new and I'm having the same problem with the dash lights not coming on. I see by reading this comment, that there was a warranty enhancement. I don't exactly what that means? My car didn't start doing this until around 2018. If there was a recall of any sort, I certainly never received one but I don't believe that's what the warranty thing is about. It sounds like if this had happened while the car was still under some kind of warranty period, it would've been covered but obviously, the car is going on 13 yrs old, way past any warranty period. Guess I'm screwed, huh? Other than the dash problem, the car is chuggin right along

 

I purchased my a 2007 Prius used. He's blue so I named him after a dog we use to have growing up, "Blueky". I've been having the same issue with the dashboard lights. I've replaced the 12v battery in the back and have reset the battery numerous times after watching YouTube "dashboard light resolution" videos. The trunk won't open when the dashboard lights aren't on so I have to open the back seat and remove the lock cover and tire hatch cover to get to the battery. I remove the red cover to the battery then the white clip plug in for a minimum of 30 sec plug it back in. Dashboard lights come on and if im lucky they'll stay on for a whopping 24hrs. My odometer hasn't moved from 245,999mi. Im thinking combination meter but would have to get my dad to do it.... is it easy or labor intensive? Any tips or ideas of where to go next would be helpful. Thanks in advance!

 

I fixed mine the other day and was amazed how fast and easy it was. replace the 100 cap with a 220. use the search function to find the how to. YouTube has a great video on removing it. Took about 30 minutes to remove the dash, 5 min to solder the cap in and 30 minutes to snap it back together. YouTube search cluster removal, and cluster repair.

 

hi
I also have same Robles in my car n for temporary basis I unplug the battery cable n it works but problem was still there then I put the new battery but problem was still there, meanwhile this whole activity I realize that when I was opening left side door on first attempt then dashboard lights was staying on n when I was driver side door then dashboard light was going off so I change the left side DOOR LIGHT SWITCH after which my car is ok and I have no problem at all so if anyone has any problem like this please try to change the door light switch then check it .
Thanks

 

With right side door light was staying on n with left side door dashboard light was going off so I change driver side door light switch after which problem is solved.
