Many thanks for your speedy response. It confirmed my fears. However, I was told by another person that the sensors mid cabin, may not be talking to main sensor on dash! How much should I be prepared to spend to: .... 1. get sustem re-charged, repair sensors, and worst scenario? It may be useful to know that I only drive car 1 day aweek, but it's my pride & joy and want her to function perfectly!
I appreciate your expertise.
