In Reply to: Heater Valve Replacement - Whole Thing or Kit? posted by Troy on October 08, 2001 at 11:09:57:

My heater control valves seem to be sticky - sometimes I get nothing but full blast heat even when I set the Temp dials to full cool. Other times the vents blow cool air, but do not respond to the control dials on the dash unless I turn the dials to full heat.

My question is - should I replace the entire heater control unit (the unit that the coolant hoses go to - not the dash microprocessor) or use the heater valve replacement kit that I've seen for sale.

I'm reasonably handy and could do either - just interested in spending as little time as possible on this. I need all the weekend time I can get to play with my 10 week old daughter.

Thanks in advance,

I went through this myself a couple of years ago by just replacing the kit.
Sure enough only a couple of months ago the housing gave out - actually left me stranded on a country road. Turns out from other posts that they are possibly prone to do this (at this age) anyway.

So my advice:...... don't have to end up buying or fixing something twice!!!!! Just put a whole new unit in now and you won't have that 'wondering how long' feeling.
