One Sided Heat

[colopedo]

Other than my intro, here's my first post~ got cold up here in the Northeast (NY), just in time for my heat system to get wacky on my 03 disco se7.

has the dual climate control, & I can get heat out the passenger side, but not the driver under any circumstance. Only way to get some warmth is to divert heat to the dash vents & keep the driver's ones closed, so at least it pumps thru the passenger vents (keeps the mrs. happy!)

Since I have heat, figure the coolant level is fine, as is the blower (since there's only one fan control I guess there's only one?); guessing there's a valve sticking? or some kind of air gate but dunno where it is. Don't wanna tear apart the dash looking for it. Hoping some of you gents mite hopefully be able to direct me if I'm on the right track or give me some shortcuts.

thanks in advance

Not sure if this helps or not... but here is the info about the distribution setup in the heater assembly.

Control flaps
Control flaps are installed in the heater assembly to control the temperature and distribution of air. Blend flaps control
the temperature and distribution flaps control the distribution.

Blend flaps:Two sets of three blend flaps, one LH and one RH, regulate the flow of air through the heater matrix and
a heater matrix bypass, to control the temperature of the air leaving the heater assembly. The two sets of blend flaps
operate independently to allow different temperatures to be set for the LH and RH outlets.
Each blend flap is attached to a spindle. The end of each spindle extends through the side of the heater casing and
is attached to a common lever mechanism on the related side of the casing. A control cable is installed between the
lever mechanism and the related temperature knob on the control panel. When the flow is split between the bypass
and the heater matrix, the two flows mix downstream of the heater matrix to produce an even air temperature at the
individual outlets.
Distribution flaps: Separate distribution flaps are installed to control the flow of air to the footwells, windscreen/side
windows and the LH and RH face level outlets. The distribution flaps are attached to spindles that extend through the
RH side of the heater casing and are attached to a common lever mechanism. A control cable is installed between
the lever mechanism and the distribution knob on the control panel.

hehe...Thanks I guess?? I't may not have been intented to be, and haven't been round to know if yer shittin me but that is one funny post. I say so cause I read over it once & my eyes crossed. Lemme try it again & see iffin I can figure what yer sayin. Probly just me...I aint too brite ; )

ok Joey, read it slowly & think it looks like a blend flap issue; either the flap (anyone got a sketch of where the one controlling the driver's side is?
or the cable (is there still a cable when there's no knob..ie..digital temp controller?)

Basically when it is digital it is vacuum IIRC... I may be able to post the pic... let me see.

Hope this helps, but not sure.

thanks much! that makes it look like it's all one big apparatus though...know if it can be dismantled?

I am sure anything can be taken apart with enough effort... and in some cases a few screws
