My heat doesnt work in my 1989 cadillac sedan deville is there a fuse I can check

SOURCE: Can not find the body control module on my 1989 cadillac sedan deville -- anyone know where it is?

you need to take glove box out. It's right behind three three 7mm bolts for the plastic piece that holds it in. two 10 mm nuts that hold it to the plastic piece. Should come right out with a little finessed force.

Firing order 1-2-7-3-4-5-6-8 ..............1-3-5-7 back of engine near fire wall...........2-4-6-8 front of near radiator

I would beleive more that you have build up in the heater core. Try taking loose the heater hoses from the block and use a water hose to spray into one of the hoses letting it come out the other hose then switch hoses with the water hose and keep reverseing for 2/3 times each hose. sounds like stop leak may have been used in a prior time and may be blocking water flow.

Good luck,

Fords have the reset switch option only. Relays are mounted on the firewall
