Heating in Renault 19

First thanks to those who provide answers that can help me. Well my heating problem in a Renault 19 Mod 94 Motor 1.7
What I did is clean the radiator,
change of water pump,
check that the duct is not clogged,
draw the thermostat,
change the bulk of the electro, (probate the direct electro)
Chequate that it is not entering compression to the refrigeration circuit.
(On the route does not heat, it remains at a normal temperature, the problem is when I grab me congestion or enter the city) Of course thank you very much and I wait for advice ...

Look if there is nothing covered in the exhaust multiple because it has a water passage through the multiple and sometimes they cover
you did not change the water hoses.
Because there are the hose that go to the heating radiator to be set. You noticed the door of your house if you raise temperature and where the needle arrives because the TBN problem can be the bulb that marks on the
good board I will continue to think where the problems can be
greetings and luck

If you do not heat up on the road then the problem is with the Kisas electrventilator enters very late or enters very soft check where it starts before doing anything, you can try putting a lower bulb to see how it behaves luck,

Control if the electrventillator works by pulling the out of outside the engine, the cables changed on the place may be going and it turns against
