Hi @PeugFra and @cbarge ! Yes thank you, I'm allright, perfectly allright. I did not received the alerts, so I read your messages only right now. I've been working on my car, with good results, I'll post upadtes very soon!
Update for the blower removal.
I finally managed to remove it , after jacking the car, removing wheel and inner fender, and all the stuff attached to different places. One hour and a half of work. Well, now the blower motor is removed, it did turn freely when removed, but now it does not anymore. I loosened the two nuts and freed a little the cover, and, when re-tightening the two nuts, it does not turn freely. Anyway, I'm gonna purchase a new one, it's only $28 or 30 @Rockauto.
But now, my problem is that I did not remove the motor resistor, and it seems to be bolted at the back of the blower motor housing. I won't try to check it, as I don't have time (and sure don't want!) to remove all the stuff again … Anybody should have a part number for the resistor? I can't find it at Rockauto.
Or anybody should tell me where I can find a new one? I think this should not be very expensive
