Blower/heater in C5

Hiya

Its me again, think i keep this forum going just on my own!!!!

have a C5 2002 2.0 HPI and apart from little stupid faults the car is running fine after changing the fuel pump and the coils which got rid of the anti-pollution fault.

Wen i put the blowers on, the passenger side blows hot even if the temp knob is on cold, the drivers side is ok, its murder wen weather is hot as cant put blowers on or i cook the passenger in the car!!

Anyone know wat could be wrong, and is it easy to fix, thanks in advance

Juliex

PS this is just using normal blowers and not the A/C

Common fault where the motorised heater flap gear strips, always on the passenger’s side.
The permanent cure is to replace the motor with an ‘updated’ one with longer gear that has a deeper reach into the flap.
It’s a very fiddly job because the motor is buried behind the heater controls.

I’m reading on the French sites that they cut into the dashboard to reach the motor.

There are topics about it here, but haven’t found any yet, so hope that those in the know aren’t far behind.

It's worth doing a reset of the body computer before delving too deeply. I've had this problem: a reset cured it, and it hasn't recurred.
