BMW Heating & Air Conditioning for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

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.

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. Race German's Heater Delete Plug was designed for E30's that have had the heater core removed. Without this plug there is a very unsightly hole in the firewall that allows for foreign objects such as water and debris to enter the cabin. This plug works perfectly as a seal and also keeps the engine bay looking clean!

Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play R134a upgrade allowing you to properly run A/C in your 24v swapped E30 without sacrificing the OEM look and feel. Using the E36 M3 Denso compressor and our Denso Compressor Manifold, this has been designed to work with the S50, S52, and S54 as well as the M50, M52, and M54 engine and comes complete with a new Denso compressor, CSF parallel flow condenser and SPAL fan, R134a expansion valve, and new R134a lines (inside and out). NOTE: All variations ship with the late model filter drier and will require this safety switch if not already fitted. Which condenser and fan should I choose? For a complete and proper conversion, we strongly recommend using our new high performance CSF parallel flow condenser and SPAL fan combo for the most efficient A/C system. If you are planning to use your original OEM fan, we recommend using the Nissens condenser. Do I need to replace my interior lines? While your original R12 lines can be used, it's highly recommended to replace all rubber lines when converting to R134a to prevent against leaks. What if my E30 didn't come factory with A/C? Our products are designed to support factory A/C models; however, they can be fitted into non-A/C applications, but you will need to obtain a factory HVAC wiring harness, high-pressure drier return line (long metal return line), evaporator, and factory interior HVAC box with sensors, control module, thermostat, etc. Note: BMW compressor bracket 64551730768 will be required to support the Denso compressor. What’s in the box? Genuine Denso E36 compressor A/C Solutions 24v Denso compressor manifold CSF parallel flow condenser w/ genuine SPAL 13" fan and hardware (optional) Nissens parallel flow condenser (optional) Interior line set (optional) Low-pressure suction line (bulkhead to compressor) High-pressure discharge line (compressor to drier) High-pressure condenser return line (condenser to drier) OE R134a filter drier R134a expansion valve R134a high-pressure adapter fitting Model specific R134a o-ring kit R134a retrofit label Wiring kit and misc. hardware Detailed installation instructions This product requires no R&D, and is easily reversible using professionally engineered components, OEM-like hardware, and durable replacement parts resulting in a trouble-free installation that can be completed in 4-6 hours by a professional. It is designed to fit factory S50, S52, and S54 headers while providing ample clearance around the factory oil cooler lines and OEM brake ducting/undertray. Proper functionality of the evaporator, expansion valve, and HVAC sensors is required for a fully functional system.
