Furnace wrote: (98 Buick Riviera Seat Heater Problem)

The Drivers seat heater doesn't work. The light comes on when
you press the "Hi" & "Lo" button but there is no heat, and a clicking
sound comes from under the seat. I replaced the heater element
with one from Autowarm.com. The connector plug didn't match
and I had to splice it in.

Result: Still shows switch light, still clicks under seat, and still no
heat.

There is an option of hooking up a new button that came with the
new element's and bypassing the old system altogether, am I better
am I better off going that route?

Check further before giving up and jury-rigging a button. An odd
button is inconvenient, looks tacky, and might not solve the problem.

A bad connection in the heater switch or its supply line could starve
an under-seat relay and cause it to click on and off (like a bad battery
cable causes a starter to click). Try bypassing the switch and
hooking up power directly. If the heater heats and the clicking
stops, the problem is in the supply circuit somewhere.

Some public libraries have manuals with wiring diagrams for cars.
Knowing what is in the heater circuit would make diagnosis easier.

Look as far under the seat as possible and re-post a with a description
of the area or better yet, the device the clicking is coming from. Also
describe the clicking; tinny or thumping, quiet or loud, and frequency
- one click per second, or faster, or very fast like buzzing?

Good luck.

A friend bought a oyear old 99 Chrysler 300 in 2000 . A wire crack off
the heating element on the driverseat. Chrysler wants $400 + to remove
and replace the heating element. No one will soder the wire
on.........so since 2003 Mikey has had a cold rearend while driving as
he isn't going to spend $400 for a new part when all it needs is a wire
repaired.
