Corolla Dasdboard Screw Up.....please Help

Hi,

My Toyota Corolla 2003 model (3 - door hatch) dashboard screws up, with all the dials displaying incorrect information and some of the lights being ON on the dashboard. It seems to me like whatever all the dials are on at the time when the fault occurs those values are set as zero and my actual values added to them, but ofcourse I coulod be wrong. For example if I am doing 30mph when the fault happens (which is random when driving) my speed reading will show 60mph and if I stop at traffic lights then it will go back to 30mph (not zero). If the fuel guage is half full then when the fault occurs then the guage will jump to full (without me adding any extra fuel). Also if I have the lights on, say at night. The dashboard lights will flash when the fault happens. If I turn off the engine and then restart the car it will fix itself but will happen randomly later on. I have taken the car to the garage and had the computer reading monitored (£40 bill) and the found nothing. Any help would be useful. I was also told that the windscreen could be leaking and hence short circuiting the wiring, but I have taken the car to windscreen experts and they say that its fine and no leaks. They also said that toyotas don't usually have windscreens leaks. The fault also happens in summer when we have not had any rain for a while. I was wondering if this isn't an issue with the dashboard but maybe a way of the car telling me that something else is wrong, like when the brakes make a sound when they are close to being empty.

PLEASE HELP ME!!!

I have no deal what to do.

Hi and welcome to TOC

Sorry to hear you're having bother. All I can suggest is that you disconnect then reconnect the clocks again. It could be something as straight forward as one of the electrical connectors a bit on the loose side.

( I'm assuming that it's not under warranty ! )

No warranty.

I have taken it to several garages and they have no idea. If it was somthing that small do you not think they would have found it?
