Heater fan not going and seems to be leak on matrix

How do you know its a leak?

cos theres water in the footwell with a slight rusty tinge to it and water level going down but not quick

Hi archangel, my heater blower stopped working a while ago. I checked all sorts and asked questions. It eventually tracked down to the ignition barrel. When I start the car and the fan does not run then I just hold the ignition key and put a small amount of upward presure on it and the fan starts ok. It has something to do with the cables on the back of the switch I think being loose or the age thing where they come loose. I have not bothered to remove anyting on mine because I am lazy. Sorry I dont know how to get the matrix out.

Matrix is a pain to remove,

the dashboard support bar gets in the way,

anyone know what size of pipe feeds from engine to heater matrix , was thinking about bypassing matrix till i can get it exchanged to keep the leaking down

iused a peice of one of them metal Broom handles,
once, its the right thickness (U-shaped loop is best imo, copper pipe and pipe bender needed for that tho)

But make sure you get all the airlocks out of it , if you by pass-it,
ive seen headgaskets blow after people have by passed Matrix, be carefull mate,

cheers lozz
better than having it blow allover the passenger side though, did that with the 306 I had , not fun !
