SPEC & OE REFERENCES — ISO 280 micro relay, 12V, 4 terminals, normally-open 20A contact, with built-in resistor; stamping #13748475. Cross-ref/OE: 68100734AA; supplier/stamping codes commonly seen: 104160102, VH28-11F24-S01. Match your relay's stamp or OE to confirm
FUNCTION & INSTALL LOCATION — Multi-purpose control relay located in the underhood power distribution/fuse box (engine-bay relay/fuse center). Restores functions when the original relay causes intermittent no-start, inoperative A/C clutch or radiator/blower fans, or random accessory power loss. Direct plug-in replacement in the under-hood fuse/relay block.
COMPLEMENTARY PARTS (sold separately) — For a complete service of the under-hood fuse/relay box, pair with micro fuses 68100746AB / 68100747AB / 68100748AB (circuit protection) and a Power ISO Relay 4671886AA (higher-load positions) where applicable. These items address adjacent circuits and common co-failures in the same panel
وصف
13748475 Micro Relay — ISO 280, 12V, 4-Pin, 20A NO (with resistor)
What it is: Compact ISO 280 micro relay used to switch key vehicle circuits. It uses a 12V coil and a normally-open 20A contact with an internal resistor to suppress voltage spikes.
Where it goes: Underhood power distribution / fuse box (engine-bay relay block). Direct plug-in design.
What it fixes: Intermittent no-start, inoperative A/C clutch or radiator/blower fan, or random accessory power loss caused by a failing micro relay.
Cross-refs: OE 68100734AA; stamp #13748475; supplier/stamping codes seen: 104160102, VH28-11F24-S01.
