matrix flush
« on: 02 March 2015, 14:35:38 »

Well I just flushed it out and reversed the flow and expected to see some discolouration... But no . The water coming out was as clear as it went in... Wasn't banking on that as the heaters are awful...  >:(

Pretty much matches my experience, should be warmer again regardless.

So what do we think is causing poor heat if the matrix is clear?

Heater bypass valve incorrectly connected or not working....

Might even have a vacuum leak, thus won't work when it needs to...

OR

Something in the dashboard had become adrift and needs reconnecting...

HBV was changed last year some time and all seems well with it. The solenoid on drivers side has come off and can't alter temp but can on passenger side.. But overall temp inside is poor.. Where would there be an air leak?? And how would that affect the temp?

Why ??? Just lift the front end of the centre console side to unkook it, then pull it away slightly and push in down... Control is right there... ::)

If you don't fix it you'll only ever have lukewarm cabin air as the driverside is stuck permanently on LO...

Ive read the " how to" on this job and seems far more complicated to do than you describe? We are talking about the same thing here?

Was the HBV fitted correctly with the pipes on the correct ports?

Is it possible to balls that up?.. Ive just found the heater module .. There's also a brass coloured rod behind it with a hook on the end bent around a plastic thing... Don't know what I'm to look for though?
