I need to get the ressitor pack out to replace it or to replace the motor (its connected to the resistor) but the life of me I can't get the The heater may stop working in Vauxhall Astra due to low coolant level or air in the cooling system, clogged heater core, bad thermostat, faulty blend door actuator, bad water pump, dirty cabin air filter, bad blower motor, or HVAC control unit malfunction. 1.

It's designed like that to protect the compressor from damage. Chances are, that is what's wrong. A lot of places offer a free check and only charge if the system requires regassing. They also won't charge if they cannot refill the Here are the most common symptoms that your Opel Astra is overheating. 1. Gauge/Temp Light. Your Astra will be equipped with a temperature warning light and/or a temperature gauge. The most common symptom of overheating is the temperature light coming on. If this light does come on, make sure that you get off the road quickly and safely. 1. Weak battery. The leading cause of clicking noise and no start in Vauxhall Astra is weak battery. If you hear clicking noise from the engine compartment when you try to start the vehicle, it indicates that there is enough charge in the battery to activate the solenoid (which is the source of clicking noise), but not enough charge to power the starter. Here’s how to about diagnosing why your AC is not turning on in your Opel Astra: 1. Inspect Your Astra’s AC/Serpentine Belt. As stated above, your Astra’s AC compressor may be turned by the serpentine belt that turns all of the engine accessories. Or, it may be turned by an independent belt. The Astra Sports Tourer Electric uses the mildly updated second version of the company’s workhorse Common Modular Platform called e-CMP2, also called EMP2 and STLA Small. This now offers 115kW If not that module is broken. It could be that your AC system is empty again, the fan doesn't run when there's not "enough" pressure in the system. Normal function: The AC fan should start after 2 minutes of the AC running or if the temp goes over 90 degrees. It doesn't need to run all the time. The AC system connects to the engine, so if the engine overheats, the AC is affected. Some typical faults can make the engine overheat and then trigger AC off due to high engine temperature. These faults and failures include; Worn-out thermostat. To properly appreciate the thermostat, you have to understand its working mechanism. Everything is fully working. When I use right indicator after few seconds I flashed quickly and I have a message check rear indicator light. Everything is fine. Plus most of the time rear light driving side are not switched on first time. After move the wheel on and off few time is working. Any idea what is wrong. Thanks. pv4Pl3.
