Toyota Innova and Crysta A/C and service in Chennai
Front vents feel cool, but passengers in the back are uncomfortable? Tell us which rows are affected and whether the rear blower runs. GM checks Innova and Crysta A/C complaints, electrical faults and general-service needs at Kallikuppam, Ambattur.

Separate rear airflow from rear cooling
A weak stream of air from the rear vents is a different complaint from strong airflow that feels warm. Describe both the airflow and temperature at the front and rear. That helps the technician check the affected area before discussing replacement parts.
Innova generations and variants differ. We confirm the A/C layout on the vehicle and check the controls, airflow and cooling performance appropriate to that system. A warm rear vent alone does not establish that a cooling coil or compressor needs replacement.
What to mention when you book
Rear vents blow weakly
Tell us whether every rear outlet is affected and whether changing the rear fan setting makes a difference. The inspection can then focus on the rear controls, blower and airflow path.
Air is strong but warm
Mention whether the front also becomes warm and whether the problem changes in traffic. Refrigerant and component checks follow the observed symptoms; a refill is not a diagnosis.
Noise appears with the A/C
Describe when the noise starts and where you hear it. We need to locate the noise before deciding whether the compressor, its drive components or another part needs attention.
Plan service around the vehicle history
Bring previous invoices, the current odometer reading and details of recent A/C repairs. If the vehicle has repeatedly needed gas, tell us when each refill happened. For an Innova Hycross, share the exact powertrain first so we can confirm the work we can accept; this page does not offer hybrid battery or drivetrain repair.
Inspection and estimate
GM starts with a free 30-point A/C and electrical checkup. We explain the findings and give you a written estimate before any paid work. Service prices depend on the inspection, parts and work you approve.
Independent workshop service
GM Car A/C Service is an independent multibrand workshop, not an authorised Toyota service centre. For manufacturer warranty claims, recalls or high-voltage battery and drivetrain work, contact the manufacturer's service network. Share hybrid or electric vehicle details before booking so we can confirm the service scope.

About this service information
Published by GM Car A/C Service. Updated . Describe your vehicle and complaint when booking; the inspection determines the repair, parts and completion estimate.
Four steps, in this order, every time
Diagnosis-first is the whole method: measure, write it down, then price it. It is also why every job, gas filling included, is quoted in writing after the checkup.
We test before we quote
The free 30-point A/C and electrical checkup runs first, about 15 minutes, with a written report of what was measured.
You get the estimate in writing
The report says what was found. Gas filling, like everything else, is quoted in writing after the checkup, and nothing starts until you approve it.
No work starts until you approve
Nothing is opened up or replaced before you say yes to the estimate. If the diagnosis changes the scope, you hear about it first.
Repaired, then checked again
The approved work is done and the car is checked again before handover.
Frequently asked questions
Can you check an Innova with cold front vents and warm rear vents?
Yes. Tell us whether rear airflow is weak or whether the air is strong but warm. We inspect the relevant controls and cooling system before recommending work.
Does a noisy Crysta A/C always need a new compressor?
No. Noise alone does not identify the faulty part. The technician needs to locate it and check the system before advising on repair or replacement.
Can I book maintenance for several Innovas?
Use the fleet service page for a business or multi-vehicle enquiry. Fleet scheduling and estimates are handled separately from individual car bookings.
Is GM an authorised Toyota service centre?
No. GM is an independent multibrand workshop in Kallikuppam, Ambattur. Contact Toyota for manufacturer warranty claims and recalls.
