Interior Heating
CITROËN C3 Picasso

@user_2148318 Jan 13, 2024MemberC3 Picasso 2011. Is there a heating element? The interior is
not heating until the engine is really hot and then I get a small amount of
warmth. Garage says there is no element as it uses a second radiator, and that
required flushing, but it was clean. Then they changed thermostat and housing
in being the last option. When I collected it, I was told it was 100% better. There
is no difference, it is still blowing cold.

@Versuffe Jan 15, 2024MemberPerhaps a problem with the heater housing or with the flaps that regulate warm and cold air in it?Reply - @user_2148318 Jan 15, 2024Member
The garage replaced the thermostat and now I get a little
warmth but only having driven 20+ miles. I asked again at the garage and they
checked the heater housing and moved the flaps. Now claiming they have checked
everything, but I do not have any heat to defrost, or keep the interior more
than just warm, so wearing a thick coat. Now told I can buy a heater that plugs
into the lighter socket, but that is not fixing the issue.Reply - @Versuffe @user_2148318 Jan 15, 2024MemberI think that there could be the air left in the system, which is why the interior does not heat up. If everything was fine before the replacement, then let the mechanic figure out what he did wrong, maybe he connected something wrong or there is air in the system.Reply

The heater issue began some 15 months ago and I went through
last winter with a small amount of warmth once the engine was hot. This winter there
was no heat at all. The thermostat was changed and I now have limited warmth
from the engine, but nothing more. The garage says it has checked everything.
They have sold may C3 Picassos with no heating issues.Reply -
@Chout1964 @user_2148318 Jan 16, 2024MemberThe problem may be in a clogged radiator, or in the resistor, as well as may not work the flaps that change the cold and hot air flowsReply

- @user_2148318 Jan 16, 2024MemberThe garage has checked the radiator and were able to move the flaps. I don’t know about the resistor, but they have diagnostic software. They claim to have checked everything. It must be something as I do not have any heat, other than when the engine is hot and it is then warm.Reply

Would the Citroen dealership have more advanced
diagnostics than the local garage who have Citroen software?Reply - @Wastfultaint @user_2148318 Jan 19, 2024MemberOf course, the dealership has better diagnostic equipment and they also have all sorts of descriptions for troubleshooting, it’s worth contacting themReply
