Ok, replaced the OVP yesterday, as noted in my SSS post.
Mike, I pushed the next button over... confirm that the A/C is not working/cooling... all I get is a little more air from the vents... like the blower kicks up a notch.
I did notice that the system is very erratic.... sometimes I get hot air from the screen vent and sometimes not... sometimes when I push the auto or high fan position I get no increase in air... and then after I hit the defrost, it works, and cycling back to the ECO or A/C button gets it working again.
I notice that sometimes after I start the car, I hear pops and noises from in the dash... but they happen, say 20 to 30 secs after when I first start the car...
The Economy gauge in the cluster is very erractic too...
Vac leak?
