every so often more so when sitting idling the coolant temp warning light flashes up on the cluster folowed by the washer warning light an the oil pressure,i no that i have a leaking washer bottle but was wondering if that could trigger the other ones to come on when it reaches low,i have drained the coolant system an put antifreeze in an also renewed coolant temp sensor aswel as the battery,could this be an electrical prob?an where would i start?

    If all the lights are coming on at the same time I would suspect an electrical problem, but I would try to rule out any possible engine overheating or low oil pressure issues to avoid engine damage.
    The instrument clusters did have some issues, you can read about them here: http://bit.ly/8z7rcm

    bretb is right on. you never said if the oil or coolant levels were ok and if the temp gauge is reading high. and the low waher fluid should not affect the other lights unless crossed wires have occured.

    o.k the temp light is flashing on followed bye the washer light {no oil pressure light) & the temp gauge will be half way as normal then will fall down to zero then after a few mins will go back to half way,this will happen for a short while then when the lights disappear an the temp gauge is back at half way the outside temp will read something crazy like -44 degrees an will drop 0.5 every 10secs or so till back to normal,p.s my oil an water levels are spot on
