BMW Electrical Sensors, Switches, & Relays

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.
