Hi Guys,

I read through the forum but could not come across the issue I am experiencing:

I finally got around to having my AC compressor and dryer replaced. System was properly serviced by professionals - when the A/C is running - the discharge temp on the driver's side is cold (both center and outer vents) - discharge temp on the passenger side center and outer vents is about 10 degrees warmer... (still cool)

One thing I noticed - the external ambient temp sensor works good and is on target sometimes (temp display) and other days - not so. (going to change it)

Cleaned the temp sensor by the ignition switch a while back with MAF cleaner - still looks good and clean.

I'm leaning towards two possibilities:

Evap temp sensor - passenger side
Blend door - passenger side.

Finally, how many evap discharge temp sensors are there for the 2000 MY? three? Where are they located?

Any help would be appreciated - thanks!

 

I would be looking into replacing the electrically controlled valve on the coolant circuit. I believe it is called the DCCV.

I think at year 2000 you will need a 5 pipe unit, the facelift cars use a 3 pipe setup.

 

Just to update this issue:

1) The DCCV is working properly - this is not causing the air flow/temperature issue I originally described.

2) I had a spare CCM I purchased a while back - I received some sort of CCM - communications error failure (I have the code stored on my device - I will update once I get it from memory) on my scanner with the old CCM when I ran a diagnostic of the climate control system. (along with 2 servo motor circuit fault error codes)

3) After installing the spare CCM - no more CCM failure code - ice cold air was coming out of all dash vents and the air flow was much much stronger.

4) I am now in the process of tracking the servo motor(s) causing the circuit fault error codes. (Check out my other post for details)

Thanks
