Went out last night to pick some people up. When the first person got in, the front the door wouldn't shut. Slammed once or twice, no joy till I got out and pulled door handle a few times and then it shut ok. Then the back doors did the same but wouldn't shut till I pressed the lock button down. However I couldn't open them again and nearly ended up with 2 x 80 year old women locked in my car forever. Luckily, one door opened, and they eventually dragged themselves out. I reckon the mechanism is frozen. Never had that before!! Any help appreciated, also, is there a 'how to' remove door linings so I can lubricate the mechanism.
