That’s all. If you have something to add – write in the comments.
Not sure if this is the right sort of comment you’re looking for but I managed to short out our car (ACR30 with 2AZ-FE), the engine will run and hazard lights will flash but the electrics are not responding, no dash/centre console, windows won’t move and no locking/unlocking, any help appreciated, all the fuses look okay
Hi Chris, did you find the cause? I have a dead instrument cluster and car won’t accelerate at all.
All fuses seem ok
