AC & Heating Diagnostics and Repair
Vehicle Diagnostics — Cheyenne, WY
In Wyoming you need both sides of the climate system to work — summer sun on the high plains and winters that turn a dead heater into a safety problem. TDC Automotive diagnoses air conditioning and heating complaints on both gas and diesel vehicles: warm AC, weak airflow, heaters that never get hot, blend doors that stick, and blower motors that quit.
AC and heating problems can be refrigerant-side, coolant-side, electrical or mechanical, so the diagnosis starts with testing — pressures, temperatures, actuators and circuits — to isolate the actual fault before any parts are recommended.
What's Included
- AC blowing warm or cycling on and off
- Heater blowing cold or overheating together with the engine
- Blower motor, blend door and actuator faults
- Gas and light-duty diesel trucks alike
- Test-based diagnosis before any parts are sold
How Trevor Diagnoses a Problem
- Verify the complaint
Before touching a wrench, Trevor reproduces the symptom you're describing — sometimes on a test drive with you in the passenger seat so you can point out exactly what you're feeling or hearing.
- Inspect the vehicle
A visual and hands-on physical inspection often reveals what a scan tool can't: chafed wiring, soot trails, wet gaskets, loose components.
- Scan for trouble codes
Diagnostic trouble codes (DTCs) narrow the search to the right system and circuit.
- Test to confirm
The suspect component gets tested and confirmed as failed before it's replaced. Then the repair is verified with a final test drive.
