Hey everyone, its been a while since ive posted as the Prelude has been going well and I have not had a need to upgrade.

I have an issue with the climate control air con and heater. The unit inside the car functions correctly but when I switch it on, the air con and heater does not switch on.

The fan does not switch on also so I basically have no heating or cooling. The fan itself is functioning as it was working two days ago but now it wont switch on. I've noticed if i hit a rather large bump on the road, it will sometimes turn on.

Wondering if anyone has experienced this problem and can point me in the right direction to repair. It seems to be electrical, something like a sensor?

Thanks in advanced.
