Hi, I'm not very good with hvac. But on a 2012 camaro the a/c is not blowing cold or even cool. Its just warm. But it is not as warm as the heat, so there is a difference in temp. I checked the blend door and the blend door actuator, and those are working fine, the compressor is kicking on also. But only for about 10 to 15 sec at a time. The in line is freezing cold and the other line is very hot. I dont know where to go from here...
Evaporator leak very common in that year camaro if that where the problem front windshield needs to come out to get to some bolts out that will hit the windshield
Have you checked the pressures in the system?
Check for a system blockage.
Yes pressure checked and all normal.
Could you tell us what the pressures are? And, is the condensor cooling fan working?
Are you sure it's not low on a charge, from your description, looks like it's low.
Joe- Always check the pressure and measure the refrigerant charge before doing anything else. A low charge can cause a whole host of issues......
Pressure and charge are good
Is the blower on high while the compressor is cycling that quickly?
Plug in a scan tool and make sure the pressure sensor reading agrees with your gauge readings. What are the actual pressures you're seeing when the compressor cycles on and off?
I will do that then tomorrow and let you know! Thanks
Joe, You need to do more than just state the pressure and charge is "good". In order for us to help you we need to know the actual system pressures, both high pressure and low pressure, vent temperature, at fan speed setting and engine rpm. These are all variables that can have a big effect on how well, or not well, an air conditioning system works. Did you check the system for trouble codes…
I work a late shift tm so ill hook my scan tool (verus pro D10) and check everything and hook up the a/c machine again and get all the info.
I think Eric has summed it up. Good is not a measure in this case but follow through with the ton of advice and questions, you will have it sorted in no time.
Very common for the air box door to break....all you scan data will look great because the actuator is moving.....just the door is not...have to remove the windshield...truly great engineering.
I agree with all , pressure information required, and have done a few of these due to blend door , dumb set up , windshield has to come out, actuator motor moves but not door
You can remove the dash and heater box without removing windshield. It is a cheat but it works and causes no damage. The 2 bolts that come down from the top which require you to remove the windshield stick through the cross bar about a half inch. If you cut those off flush using an air saw or similar tool you can pick the bolts up high enough to clear and remove dashboard aand since the bolts…
The only way to know for sure is to evacuate and do a recharge with a known good set up/scale. Both lines should be about thesame temperature in and out of evaporator, the refrigerant just changes state.
Yes, you can gain access without removal of windshield as CS stated.
