Peugeot 3008 Heater Issue

[Magiee]

Dear all,

I am first time in this Forum and I would like to say "Hi" to everybody.

I have problem with my Peugeot 3008 1.6Hdi GT 2017 95k km on clock. When I turn on heating on HI on both sides, hot air is going out from driver side vent, but from passenger side is like max 18C degree .
Kindly asking you for any suggestion. Do I have maybe warranty (since is less then 100 000km, car is from Sweden and I am living in Sweden) ?

Thank you for any help

Welcome along! I've split this off into its own topic.

On the MK2 C4 Picasso, which shares a lot with the the 3008, blockage of the heater matrix is common causing a loss of heat to the RH side of the car (so driver's side in the UK!). I suspect this is your issue. The matrix is not very expensive, and not too hard to change (although more difficult on a LHD car, you may need to remove the steering column). Unlikely there is any warranty from Peugeot, but if you've recently bought it, then there may be a warranty from the supplier - there would be in the UK.

Hi Richard, thank you very much.

I am pretty sure that C4 MK2 and 3008 have probably 1/1 same HVAC system.
What you meaning when you say heater matrix? Radiator ? I was "google" little bit and looks like actuator for "flaps" . It will be great if you can share any picture.

I bought car almost year ago, so unfortunately I don't have supplier warranty :/ .

Thank you for answer.

Matrix is the radiator inside the car. It might be a flap problem, but if you can vary the heat between cold and slightly warm, then it's more likely to be the heater matrix.

Hi All and Happy New year,

I experienced similar issue with my 3008 2019 BlueHDI 180 GT. I was on a long journey, temperature outside was around 2°C and inside was set to 23°C. Passenger side (LHS) was ok but driver side the airflow was only slightly warm from all the vents. I tried to switch direction and close and open vents but still the same. I read on forums that it's known issue in 3008 and C4 and it's heating matrix issue. Is there any way to confirm it is the matrix causing the issue before I start any repairs(Diagbox or any other method)?
TIA

Today I have replaced the radiator and everything is working perfectly. Heating on both sides is good now.
