A/C Problem

Sun Jan 17, 2016 11:34 pm

I got problem with my a/c when I start my vehicle the air from the vent is not blowing its taking around 5 to 10 min for the blower to start and as its starts most of the time I am getting the air with the heat for it and I have to increase the temperature to 30°C(86°F) and bring it back down to 20°C(68°F) for me to get the cool sometimes it starts with the cool.. When the air come with the heat I checked the a/c hose its seams cool & radiator fan is also working I think the heater might be also on .. And I have changed the cabin filter but still facing the same problem.. If any one got a solution for this problem pls help.

Where are you located? Are you trying to get heat or cooling?

If auto is turned on, what if you turn that off? I almost NEVER use auto. (On many ICEVs w/auto climate control, if you use auto and turn on the heat, they intentionally do not turn on the fan until there is sufficient heat, instead of blasting you w/cold air.)

'13 Leaf SV w/premium (owned)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I think it's pretty obvious you have some sort of A/C compressor problem. Doesn't matter if you're in "auto" or not, or if you think the heat is on: if it's warm outside and you're not getting cold air, time for a trip to the repair shop.

What year and model Leaf? It might be a control problem if you must raise temperature setting and then lower it to get cool air. What happens if you set temperature as low as possible? Is the A/C light on?

If the controls think you are requesting heat on a 2011 or 2012 Leaf (with heated fluid circulating system), they will delay the blower motor start for a little time (should only be a couple of minutes) to allow the water tank to heat up. The later cars with the dry heater in the dash have little delay. There should be little on no delay of the blower for cooling.

If you have something like Leaf Spy to read DTCs (diagnostic trouble codes), any error codes found may give some help. Temperature sensors for outside temperature, interior temperature, and heater fluid temperature are two-wire sensors which vary their resistance with temperature. They are easily accessible and can be easily checked with a digital multimeter. The A/C evaporator temperature sensor is similar, but it is harder to access. I would check for loose wiring connections in the entire HVAC control system and check the resistance of the temperature sensors. I would check DTCs before replacing expensive components.
