Couple things

[baize]

Bonnet not latching on properly. Push I down it clicks but if you pull up it comes off the latch again.

Intermittent blower. The heater and everything works but no blower. Had this problem 2 years ago, I took it to Renault they sorted it out and now it's back.

What do

I've read many times that most Renault dealers will replace a dodgy bonnet catch free of charge, due to the bad publicity they had with Watchdog etc over the bonnets flying open, hopefully shouldn't cost you anything
