- For
- DIY car and truck owners troubleshooting relay problems
- Worth noticing
- The fit guide flags micro-fit as still being tested and warns that some wide-blade relays do not fit.
Field notes
The troubleshooting guide connects vehicle symptoms to likely relay locations and next checks; for a radiator fan, it points to the under-hood fuse box and suggests checking the fuse, fan plug, and motor if the relay passes. The fit guide says mini relays fit, micro fit is still being tested, and some Ford, Ram, Jeep, and Toyota models use incompatible wide-blade relays. The page also notes that a passing bench test does not rule out a problem under motor load.
