07 3500 5.9L Hazard lights not flashing

[ridenby]

Have pulled plastic of dash and looked for flasher relays. Found none. Turn signals operate. The hazards do not. What the heck. Help , please.

Your emergency flasher relay is in the TIPM (fuse box) under hood.

Does that mean I need to replace the TIPM? I see no location for hazzard relay.

Not necessarily, you need to do some diagnostic work. It could be just a bad relay in there.

Follow up on this. Went through fuse box under hood and replaced all fuses. One to cigar lighter and another I do not recall were blown. Still no flashers. Ran across utube concerning flashers, said the multi-function switch can cause this. Cheaper , easier than replacing TIPM as the flasher relays are integrated into TIPM. Replaced with the lowest cost switch I found. It works as it should.
