My remote central locking does not work on my 03 Vxhall Zafira 1.6 club ,the rear p/ger doors stoped working firstly now all doors wont . I now use key manualy to enter car which still only opens front and boot doors not rear p/ger doors. Is there a relay to replace or quickfix . Also the heater and air con have never been that good on my car since i got it, is this the norm or onother fault

Hi
Try resetting remote, Turn key to position two in ignition and press both button's on key at same time....All doors should lock then unlock. If that does not work it could be the transponder in the key, cost's around £90 for a new one . Heater/aircon.... Try changing the pollen filter to allow hot/cold air into the cab.... situated at back of centre console glove box side (which you have to remove to get to) cost's about £15 and most place's you have to order them.
