hello to all thanks phil i hope i can sort it
hi clossie its both the drivers and pass seats i have checked all the wireing under the seats it all seems ok and the bulb in the cluster the drivers flashes with the ignition on and the pass work by using a presure sencer in the seat
iv spoke to a teck from birmingham lexus (great bunch of people)and he said it could be the switch in the seatbelt catch it is not a open close switch it works off resistence thats why the meter cant read anything
if any one is thinking of removing a seat can you disconnect the catch and put ignition on and see if the seatbelt warning light flashes (please be carefull there is an airbag connecter under the seat i think its the yellow one DO NOT dissconect it but if you are removing a seat i would be interested to know i am going to order one from lexus on monday but thay have to send off for it
thanks for all your help and keep driving
p.s give the lexus a flash when you pass one
