Smoke inside cabin

[pug rallye 0]

Hi all, just a quick question.

Ive got a Peugeot 205 Rallye 1.4 rally car and sometimes when I put my foot hard down and go through the gears, smoke/steam starts to appear from behind the dashboard mainly on the drivers side but there isnt a burning smell or anything like that . I did think it was the alternator but I have already replaced the knackered 50 amp one with a 70 amp one as we want to run a lamp pod etc. The smoke/steam doesn't occur all the time. Please could someone enlighten me as to what is causing this problem and how I can resolve it?

 

Thanks

Is your heater matrix leaking when the cooling system builds up pressure?

Hi, no the matrix doesn't leak when the cooling system builds up pressure. For some reason, the heater just doesn't work at all.
