Heating Problem
#61
Glad you got your heat back, and I hope the bender wasn't too bad. Once the accident damage is sorted, you probably should take a look at your expansion tank. There's a good possibility it is fractured and letting coolant seep out. Check the bottom of the car right behind the LF wheel for the pink residue.
Cheers,

Damn! It just never ends, does it?? What a Christmas present.

Just wanted to give you all an update, I now have heat. I replaced the DCCV today and I must say it was a royal pain. I R&R the valve from the top and I found it had 2-10mm bolts not one 8mm as indicated on a few procedures. I took the old valve apart and found no clogging in any part of the valve. I was as clean as a whistle. It appears to me that one of the rubber solenoid bladders developed a leak causing coolant to reach the head of the valve piston preventing it from moving that resulted in a no heat. At times I would get a little heat in the early stages of driving but it was only for a moment.
I will be providing additional information on my page and will let you know when it is posted.

i'm really happy nothing happened to, the other driver was complaining of chest pains, maybe because his airbag came out. i'll keep you guys updated.

As you know I replaced my DCCV and I now have heat. I put the procedure on my page along with an evaluation of the DCCV problem. I hope this helps!

I haven't torn one of those valves apart as yet, now I don't have to!

heat problem
Yes, i have. My service manual states that one side of the heater core provides heat to the drivers side and the other side provides heat to the passengers side. Thats why i thought maybe it is a heater core problem. maybe im not understanding the connection between the heater core and the DCCV .......

Wind the heat up to max (HI) and if it doesn't change and especially if that hose doesn't then chances are it's the DCCV. If you're up to it, check the voltages on its two sides. If they swing the same as you ask for very different heat then it's the valve. If they don't move alike then probably the module.

The routine is to get the DCCV right, see if the control panel can control the new valve properly, if so, see if the heat is still weak on one side. If it is, the heater core is the final culprit. Obviously, if the panel doesn't operate the DCCV correctly, it will have to be addressed.
Good luck!

J have been reading all I can from this post and others and my heat problem seems to be different- heat is equal from passenger to driver but poor and since a cold snap last week very poor- I noticed that while I am driving I get some heat but it blows cold when I stop. Also it seems that the outer vents by the doors are much hotter than the centre vents which do not throw much if any heat- ac in summer was ok. This is only my second winter and it has always taken along time to warm up with no heat until temp gauge is in the middle. My mech suspects the dccv but I cannot afford to repalce the wrong part.
