Nissan Micra: Air Conditioner Not Cold → Diagnosis

One of the most inconvenient vehicular problems is when the A/C won’t blow cold air. If your Nissan Micra isn’t keeping you cool, we’ve outlined some of the most common reasons why this might be happening.

The only thing that the air conditioning system has in common with the heater is that they both use the climate controls and the blower motor. It is entirely possible for your Micra’s heater to work just fine even when the air conditioner is not blowing cold at all. That’s why troubleshooting the air conditioner is totally different than troubleshooting the heater.

Nissan Micra Air Conditioning Not Blowing Cold Causes

  • Lack of Refrigerant– Your Micra’s air conditioner will not work if the refrigerant has disappeared due to a leak. In fact, most won’t even cycle on without the right amount of refrigerant pressure. This is far and away the most common reason that your Micra’s air conditioner is not functioning. It can be tempting to just get more coolant and get back on the road, but unless you find where the leak is coming from it’ll eventually happen again.
  • Bad Condenser– If your condenser has taken damage or been clogged up, the coolant can’t transform the
  • Clutch Cycling Switch– A/C systems use an electromagnetic clutch to activate the compressor. When this switch fails your air conditioning is dead in the water.
  • Blower Motor– If there is no air blowing from your Micra at all, the blower motor is at fault. They are not that expensive and are easy to replace (most of the time).
  • Blend Door– The blend door controls how much air conditioned and heated air enters the cabin. If it gets jammed or locks up, your Micra can’t respond to your temperature change request.

These are a few of the most common issues that could cause your Micra to not blow cold enough. There are other issues that can cause this as well.

Conclusion: A/C Not Blowing Cold Nissan Micra

Most of the time, when your Micra’s air isn’t blowing cold enough, it is going to be a lack of refrigerant causing the problem. We recommend having a professional recharge your A/C if it does end up being a coolant issue. If you put too much coolant into the system, you can really do some damage.
