I've done a little LVC website research on the DCCV and I think I have this one correct, just in case I'd like to ask the experts.
Situation:
- Air on drivers side is cool, passenger is not cool. Not hot.....just not cooled. If I was to drive on a hot day though I'm ok as the driver in the car so it IS cooling somewhat. I hopped back in my 2000 on a hot summer day and the air is definitely colder on both sides.
- DATC module self-test results were 1265 only on my 2004 LS, so NBD
- I checked the fuse just in case and it's fine (Yes, I know it wouldn't cool if blown but it's a free check ya know?)
In an earlier thread, joegr said, "If the passenger side is hot, and not just not-cooled, then it is the DCCV and not a low refrigerant issue.
A bad DCCV, even if it is just the passenger half, will still keep the driver's side from blowing very cold air."
My guess on how I should proceed:
First:
Have the refrigerant level checked. If low then charging should fix it. Strange since the car is low miles. Can the refrigerant leak on a car with super low miles? Is it normal on these cars for low refrigerant to be felt on the passenger side first?
Second:
If that is fine then I should check the resistance on the DCCM coils to see if they are < 24 Ohms. Check 1-2 and 2-3.
Third:
If everything above checks out ok then I remember reading that one easy way to check the DCCV as the cause is to crimp off some of the hoses going to the dccv and see if all of the sudden the air gets cold again. I checked http://deneau.info/ls/ and I don't see that diagnostic step in there. I think it was joegr again, but darn if I can't find that post again now. Does anyone know this way to check things out?
How did I do?
