Quick answer
When the air-conditioning in a GWM POER blows warm, cools only on the move, or the airflow is weak, possible causes include a low refrigerant charge from a leak, a compressor or pressure-switch fault, a condenser blocked by sand, a clogged cabin filter or a failing blower motor. The double cab has a long cabin to cool and often works in dust, which speeds up filter and condenser clogging. Have the refrigerant side checked by a qualified workshop, then send ShipMyPart your VIN to source the matching part.
Scope of this A/C guide
This page covers the gasoline POER double-cabin pickup listed by GWM UAE: GW4C20B 2.0-litre turbo, 8-speed automatic, 4WD with differential lock. ShipMyPart has not verified the refrigerant type, charge quantity or A/C system layout for the POER, and this page does not quote them. Where a part differs between builds, the VIN decides.

A/C complaints POER owners describe
| Complaint | Likely area |
|---|---|
| Cold at speed, warm at the lights | Condenser airflow or the cooling fan |
| Strong fan noise, little air from the vents | Cabin air filter or blower |
| No air at all on some fan speeds | Blower motor or its resistor and wiring |
| Air never turns cold, compressor silent | Refrigerant charge, pressure switch or compressor |
| Rear seats stay warm while the front cools | Overall capacity or airflow; check what your trim has |
| Musty smell, mist from vents | Evaporator and drain, cabin filter |
Possible causes in the POER A/C circuit
Possible causes include a slow leak at a refrigerant hose joint, which lets the charge fall until the pressure switch stops the compressor; a compressor that is worn or not engaging; a condenser in front of the radiator caked with sand and insects after desert driving; an expansion valve that meters the flow incorrectly; or an evaporator leak inside the dash. On the airflow side, a blocked cabin filter or a weak blower can make a healthy system feel warm. A workshop with gauges is needed to tell these apart.
Where each A/C part sits in the pickup
| Part | Location and job on the POER | Clue that points to it |
|---|---|---|
| Compressor (and clutch if your unit has one) | Belt-driven on the 2.0T engine, pumps refrigerant round the loop | Silence when A/C is selected, rumble or squeal |
| Condenser | Ahead of the radiator behind the grille, first to catch sand | Cooling fades whenever the truck stands still |
| Expansion valve | At the bulkhead, meters refrigerant into the dash | Frosting pipes, cooling that comes and goes |
| Evaporator | Inside the dashboard of the double cab | Musty smell, oily residue, slow loss of charge |
| Pressure switch | On the high-pressure line | Compressor cuts in and out rapidly |
| Refrigerant hoses | Run across the engine bay, rubbed by vibration on rough tracks | Dye or oil stains at crimped joints |
| Blower motor and cabin filter | Behind the glovebox area, move air into the cabin | Weak flow, dead fan speeds, dust smell |
Five checks before visiting a workshop
- Set the A/C to recirculate, full cold and a high fan speed, then feel whether airflow is strong at every vent.
- With the engine running, listen at the front for the compressor engaging; a click or a change in idle is normal.
- Look through the grille at the condenser: sand, mud and leaves block it quickly.
- Check the cabin filter if your owner’s manual shows easy access; a dust-packed filter is common in a working pickup.
- Note whether cooling is worse when stationary, after a desert trip, or on the hottest afternoons.
Do not open refrigerant lines or add refrigerant from a can; the system is under pressure.
When a workshop visit cannot wait
See a qualified workshop promptly if the compressor makes grinding or squealing noises, if you notice oily residue at A/C joints, or if the engine temperature rises whenever the A/C is on. Stop and switch the A/C off if the compressor belt screeches or smoke appears. A warm cabin in a UAE summer is also a safety matter for children and older passengers, so do not postpone a failed system.
Dust, tray work and summer cabins
The POER often works on sites and sand tracks, and every trip pushes fine dust into the condenser fins and the cabin filter. The double cab also has to cool five occupants on long highway runs between emirates. Rinsing the condenser gently after dusty use and replacing the filter more often than in a city car helps the system cope with UAE summers.
A/C parts sourcing for the POER
An A/C repair on a double-cab pickup rarely involves one item alone: a replacement condenser normally goes in with fresh seals, and a seized compressor can bring the expansion valve and a hose with it. Tell ShipMyPart which items the workshop listed, send the POER VIN and, if you can, a photo of the compressor label. We check the fit for your truck, quote the set together and arrange delivery anywhere in the UAE. Filters, lamps and other POER categories are on the GWM POER spare parts hub.

Frequently asked questions
Why does my POER A/C cool only while driving?
That pattern can indicate poor condenser airflow, for example a blocked condenser or a cooling-fan fault. A workshop should confirm it.
Can I recharge the POER A/C myself?
Not recommended. The refrigerant type and charge are not verified by ShipMyPart, and the system is under pressure; use a qualified workshop.
How do I know if the compressor has failed?
Possible signs include no click when the A/C is switched on, noise from the compressor, or no cooling at all, but low refrigerant can look the same. Gauge testing confirms it.
Why is the airflow so weak from my POER vents?
A clogged cabin air filter or a weak blower motor are possible causes.
Does dust affect the POER A/C?
Yes. Sand and dust clog the condenser and cabin filter, which reduces cooling.
Can ShipMyPart supply a condenser or compressor for the POER?
Yes. Send the VIN and we match and quote the part with UAE delivery.
