Took mine apart 3 times and put everything back together without any issues with them clips. You must use locking pliers or grip pliers to squeeze two plastic parts together before installing the metal clips. Also you can clean terminals and PCB and resolder all terminals. If no other components failed, it will do a trick. On mine it failed on same crappy terminals, but also it arced inside and damaged few other components and blew 30A fuse in DC/DC module. It took me a while to get it sorted, but it's up and running again. No need for a new one.
Interesting that this is repairable. Mine blew recently. It took out my precharge resistor which ive replaced via a mod using cy control cable to put the resistor in an insulated metal ip rated project box that now lives near the safety disconnect by the passenger footwell. Its disconnects using sp21 aviation connectors so that the precharger resistor can be refitted at a bench away from the car and the HV. Crazy how much work it is to replace these parts.
I just resoldered mine and got it back together OK. The trick was to hook the top part of the clip on then while holding it in place gently tap the top of the clip with a small hammer. Most of them went on really easily. Mine was in really good nick but I plan to use it in an EV conversion so figured I should have a look before it caused a problem.
The same heater was used on the 2011-2017 Renault Kangoo Z.E. in 2018 they went over to a diesel heater instead that was much more efficient and gives out better heat.
I can only comment on UK spec Kangoos, but the diesel heater is an additional spec option which is rarely seen in the UK. As standard the 33kWh Kangoos from late 2017 still have PTC heaters. However, I think if air conditioning is specified, then you get a heat pump heating system rather than a PTC.
The general consensus is no. Once apart the unit is generally unable to be reassembled. I spent a massive amount of time trying to put the broken one together with no success. I'm of the impression that these are held together at machine level pressure to get the clips on. In addition, even if itcwas easy to reassemble, the board is burned from the high current.

So is it possible to solder the little metal pieces/clips back onto the green circuit board to fix the PTC heater?

@@wolfman9999999 Ok, thanks for the reply & for making the video.
Do you still this laying around? I’m looking for a broken one so I can use the housing.
This was scrapped several years ago, sorry.
