Specs + OE cross-refs: 12V coil, SPDT (1 Form C) 5-pin (30/85/86/87/87a), mini 280/ISO footprint; rated to 30A; dust-cover style. Cross-reference numbers include 12077864, 12193611, 12193620, 12193601, 12135000, 15495778, 0 332 208 150, 931410087, G8W-1C6T-R-DC12. Match by OE# and 5-pin cavity before purchase.
Install & location (with checks): Drops into the under-hood fuse/relay box (engine compartment). Use the box-lid diagram/owner's manual to identify the A/C clutch or blower relay cavity; common on full-size GM trucks/SUVs. If the A/C clutch won't engage, or blower only works on some speeds, inspect/replace this relay.

وصف
What it is: VF28-35F14-Z01 automotive relay for 12V systems, SPDT (1 Form C) 5-pin mini ISO/280 footprint. Contact rating up to 30A; terminals 30/85/86/87/87a. Designed for blower, A/C clutch, fuel/aux circuits in compatible vehicles.
Core specifications: 12V coil; SPDT changeover; mini 280 plug-in; dust-cover style. Rated for high inrush; typical terminal layout matches ISO 5-pin cavities in under-hood fuse/relay centers.
Cross-reference numbers: 12077864; 12193611; 12193620; 12193601; 12135000; 15495778; 0 332 208 150; 931410087; G8W-1C6T-R-DC12. Always confirm by OE# and by the printed cavity diagram before purchase/installation.
Installation location: Engine-bay fuse/relay box (vehicle-specific slot for A/C clutch or blower relay). Pull straight up to remove the old relay; align pins and press to seat. If unsure, follow the fuse-box lid diagram or owner's manual.
Functions & symptoms addressed: Restores switching for A/C compressor clutch and/or HVAC blower high-speed where specified. Helps resolve no-A/C-engage, intermittent blower power, or high-speed-only faults when the relay is the root cause.
What's included: 1× 5-pin relay (no bracket or harness). Packaging and markings may vary by production lot; electrical form/fit/function per the specs above.
Fitment guidance: Use the OE numbers and your relay cavity call-out to confirm compatibility with Compatible with Chevrolet/GMC full-size trucks/SUVs and vans listed in the bullets. If your vehicle appears in those families and uses the same OE#, this relay is the intended drop-in.
