Air conditioning & Electrical Systems

When your vehicle's air conditioning stops blowing cold or you experience electrical issues like dim lights or a dead battery, the problem may run deeper than you think. At Blue’s Transmission, we offer complete diagnostics and repairs for both climate-control systems and electrical components. Whether you're dealing with a failed compressor, a faulty sensor, or wiring issues, we have the tools and experience to get everything working again—reliably and efficiently.

Air Conditioning & Heating System Repairs

A functioning A/C system is essential for staying comfortable during Inland Empire and greater Southern California hot summers and crisp winters. If your A/C is blowing warm air, cycling on and off, or failing to turn on altogether, we’ll pinpoint the issue quickly.


Our climate-control services include:

– A/C system diagnostics and performance checks

– Refrigerant recharging (R134a and R1234yf)

– Compressor, condenser, and evaporator replacement

– Heater core and blower motor repair

– Cabin air filter replacement for clean airflow


We use professional-grade equipment to detect leaks, identify pressure issues, and ensure your system is cooling and heating as it should.

Battery Testing and Replacement

Your vehicle’s battery powers the starter, ignition, and all electrical systems. If your engine is slow to crank or your dashboard lights flicker, a weak battery may be to blame.


Our battery services include:

– Load testing to assess battery health

– Corrosion cleaning and terminal replacement

– New battery installation with proper cold-cranking amps

– Charging system inspection to check alternator output


We carry quality replacement batteries suited to your vehicle’s make and model, installed and tested on-site in our Inland Empire and greater Southern California facility.

Alternator and Starter Services

The alternator keeps your battery charged while driving, and the starter gets your engine going. If either part fails, you may find yourself stranded or unable to restart your vehicle after stopping.


Common symptoms of alternator or starter problems include:

– Dim or flickering headlights

– Dead battery despite recent replacement

– Clicking sound or no crank when turning the key

– Battery warning light illuminated



We can test and replace failing alternators, starters, and related components to restore reliable operation and charging function.

Lighting, Wiring, and Electrical Troubleshooting

Modern vehicles rely on complex wiring systems that power everything from interior lights and sensors to power windows and ignition systems. When something goes wrong, you need precise electrical diagnostics to find the source.


Our electrical system repairs cover:

– Faulty headlight and taillight circuits

– Blown fuses and damaged relays

– Wiring harness repairs

– Power lock, window, and seat system issues

– Dashboard gauge and warning light problems



Using advanced tools, we isolate shorts, breaks, or module faults and perform permanent, code-compliant repairs.

Signs You Need A/C or Electrical Service

Climate and electrical problems often show subtle symptoms before they become serious. If you're driving around Inland Empire and greater Southern California and notice any of the following signs, it's time to get checked out:


Watch for:

– Warm air from vents when A/C is on

– Dashboard warning lights or unusual electrical activity

– Power windows or locks failing intermittently

– Unexplained battery drains or slow cranking

– Interior fan doesn’t respond to controls


Delaying service on climate or electrical systems can lead to bigger issues, from full system failure to battery replacement or wiring damage.
