blend door repair.

I just ordered the heater treater pro plus recirc kit. I'm having the a/c discharged at my local shop and have a warm garage to pull the dash.

My jeep has 165 000 kms. I know its recommended to replace the heater core and ac evap, but cash is tight. Is there any real way to judge how much life these parts have left in them. I have always had good heat and a/c before the blend door failed. But spending another $200 cdn on these parts is it really worth it? Can anyone comment on their own experiences?

Any tips and advice before undertaking this job would be much appreciated as well.

I wouldn't worry about the re-circ door. How often do you really use it? If it does break, you can just take it out through the blower motor hole.

I would go ahead and pony up for the heater core though. It will not be any more work.

That said, if you have maintained the cooling system with proper flushes and fluids, then with 165K kms, I would think it would be in OK shape if you want to leave it.

if you do not know the history of the cooling system, or you did not maintain it, go ahead and spend the extra and replace the core. If the system was maintained, leave the core alone.
