Keep your A/C compressor switching on command with the Standard Ignition A/C Clutch Relay / A/C Compressor Control Relay / HVAC Temperature Delay Relay (RY-270). This relay uses a low-current control signal to close the higher-current circuit that energizes the A/C compressor clutch coil, engaging the compressor when the system is switched on. It's a direct-fit replacement for a wide range of Dodge vans and trucks — the 1990-1994 Dodge B150, B250 and B350; the 1995-1997 Dodge B1500, B2500 and B3500; the 1994-1996 Dodge RAM 1500, RAM 2500 and RAM 3500; the 1995-1996 RAM 1500 VAN; and the 1996 RAM 2500 VAN and RAM 3500 VAN. See the Buyer's Guide tab for the full list. Each listed application uses one relay.

  • Switches the compressor clutch circuit: a low-current signal energizes the relay, closing the load-side circuit that feeds the A/C compressor clutch coil.
  • Direct-fit replacement: installs in place of the original relay on the listed Dodge applications.
  • Listed under multiple names: cataloged as an A/C Clutch Relay, A/C Compressor Control Relay and HVAC Temperature Delay Relay — all the same MPN RY-270.
  • Signs this part may need replacing: A/C that won't engage, intermittent compressor operation, or a clutch that won't click on — if a failed relay is the cause.

Manufacturer part number RY-270.

Frequently Asked Questions

What does the RY-270 relay do?

It uses a low-current control signal to switch the higher-current circuit that energizes the A/C compressor clutch coil, engaging the compressor when the A/C is switched on.

Which vehicles does RY-270 fit?

It's a direct-fit for many Dodge vans and trucks, including 1990-1994 B150/B250/B350, 1995-1997 B1500/B2500/B3500, and 1994-1996 RAM 1500/2500/3500. See the Buyer's Guide tab for the full list.

Why is it listed under three names?

The catalog lists it as an A/C Clutch Relay, an A/C Compressor Control Relay and an HVAC Temperature Delay Relay — all the same part, MPN RY-270.

What are signs this relay may need replacing?

A/C that won't engage, intermittent compressor operation, or a clutch that won't click on when the system is turned on — if a failed relay is the cause. Diagnose the circuit before replacing.

How many relays do I need?

Each listed application uses one relay, and this listing is for one.
