Special Features

  • Specs & OE refs — 12V DC micro relay, 4-pin SPST plug-in (Micro ISO 280 footprint); typically listed at up to 35A by sellers. Cross/related GM OEs commonly seen with this form factor: 13502749 (4-pin), 13502752 (4-pin, commonly referenced as a newer number), family numbers 13502750/13502751/13502753 (verify pin layout before ordering). Match pin count and cavity before use
  • Operation & install location — Compatible with GM applications where a 4-pin micro relay is specified for accessory-power functions. Typical locations include the interior fuse/relay block by the driver's left knee (often used for a RAP/“retained accessory power” relay) and the under-hood fuse/relay center. Pull the old relay straight out, seat the new relay fully; disconnect 12V negative terminal before service; confirm cavity label with the owner's manual.
  • Symptoms this relay addresses (examples) — Compatible with cases where a failed accessory-power micro relay causes 12V power outlets to be inoperative (RAP circuit) or where window circuits rely on a similar micro relay in the fuse box. If your aux sockets don't power on with ignition/accessory or power windows stop working while fuses are OK, inspect the specified relay cavity and replace as needed.
  • Compatibility guidance (how to confirm fit) — Compatible with select Chevrolet/GMC/Buick/Cadillac vehicles that explicitly call out GM 13502749 or its listed successor 13502752 for a 4-pin micro relay slot. Examples documented in owner/forum/service discussions include: Compatible with 2017 Chevrolet Volt RAP relay (driver's-knee fuse panel) and Compatible with Chevrolet Express 3500 window-circuit relay (under-hood fuse box). Always match your OE number, pin count, and fuse-box legend.
  • Complementary items (for a complete fix) — Compatible with maintenance where related micro relays are serviced together (e.g., 5-pin companion in the same block, often sold under GM family numbers like 13502750/13502751) and with service of fuse-box assemblies where some relays are PCB-integrated. If heat damage or corrosion is present, also inspect the fuse block and nearby multi-purpose relays (e.g., later GM multi-purpose relay families) for replacement.

Description

What it is: GM-style micro relay, 12V DC, 4-pin SPST, plug-in (Micro ISO 280 footprint). Designed for accessory-power tasks such as RAP (retained accessory power) and 12V power outlets where specified by your vehicle.
OE references: 13502749 (4-pin). Commonly cited successor: 13502752 (4-pin). Related family numbers that may appear in the same fuse block: 13502750/13502751/13502753 (verify pin layout and function before use).
Typical locations: Interior fuse/relay block near the driver's knee; under-hood fuse/relay center. Always confirm the exact cavity using the fuse-box legend and your service/owner manual.
Typical symptoms: 12V outlets inoperative on ACC/ON (RAP circuit issue), or window circuit not powering even though fuses check out. Replace the specified relay after testing.
Installation notes: Disconnect the negative battery cable. Pull the old relay straight out, align pins, and seat the new relay fully. Inspect terminals for heat or corrosion and replace damaged components.
Fitment confirmation: Match your vehicle's OE number and the relay's 4-pin layout. Use the fuse-box label or service diagram to ensure the correct position and function.
