BMW Heating & Air Conditioning for BMW E34 M5 S38 3.5L

Clear BMW chassis

Please ensure your correct model is selected

Is your BMW blowing hot air when you want AC? Not getting enough hot air when it's cold out? Well we have the heater cores, heater valves, blower motors and related parts for your BMW. Tip: Is your air conditioning / heater fan going crazy? Does it only run at one speed or not work at all? Then a likely culprit is this blower resistor, often called the "final stage unit" in the BMW world. The function of this part is to regulate the voltage of the blower motor on BMWs which use the digital climate control. This blower resistor is a notorious weakness on the cars that use it. When it fails, your blower fan speed can fluctuate as if it has a mind of its own, or get stuck at one position. BMW has updated this item several times and we only carry the most current version.

Designed to work with our ACS Sanden Compressor Bracket, these new (unused), genuine (green-label) Sanden compressors are direct from Singapore and built for high-stressed applications. The 508 series is a proven design that results in durable, efficient, and near-silent A/C that has been the basis for all of our signature plug-and-play conversion kits. The suction and discharge ports use SAE #10 and #8 fittings, respectively, and the compressor comes pre-filled with PAG oil. Note: A larger v-belt will be required (13x875mm Gates #9345). If you are planning to use this with our E30 Sanden line set, you will need the rear exit Sanden compressor instead.

Have a leak in your A/C system but can't find it? The evaporator allows the refrigerant within the A/C system to lose pressure and cool down, allowing it to transfer that chill to the air coming out of the dash vents. If leaking, the A/C system will lose refrigerant and not function how it should.
