Little red door jam lights

should come on when a door is opened. remove the 2 screws and pull the assembly from the hole. The lens and shroud can slide off the socket to replace the bulb if needed.
If the buld and everything there looks good, the problem may be in the door jamb at the switch(button). You can gently pry that out to look at the connection. It is possible that there is corrosion on one or both sides of the assembly. The drives side has 2 on the jamb.

 

doug,is right,I had this problem and fixed both. open the door,at the hinge there 2 screws on the black plate take the plate off and push the button out,clean the surface on the conectionand make sure theres enough spring that pushing in the white button that it pops back,then put everything back,I did have to replace one of them, www.ferrparts.com does have used ones and new ones if you need them,sorry I don't have pictures

 

Mine did'nt work either pulled out the assembly and of course a little corrosion,cleaned up the bulbs and there working again.

 

Use care! They are just plastic sleeves with lamps inside. However, the insulation on the connectors has often been hot and can shrink back from the connectors. Those connectors can short out against the metal hole of the door and cause untold problems. My '79 308GTB's connectors were completely BARE. Fortunately I had the battery disconnected and was working from the inside of the door. -rick

 

unplug the wire to the white housong and push the unit out ward it will be then in your hands

 

While you are there, if the rubber O-ring around the base of the light is crackedbroken/missing, measure the inside dia of the base and get a couple of rings at the local parts store. Thats what I did when I was working on my lights. For thoses of you that have your cars judged at shows, those O-rings are worth an extra 1/2 point.

 

The plumbing dept, in hardware stores, can also be a good source for O-rings.

 

if you have to replace the door switch get the porsche ones. i think there's a thread with the part numbers. i looked for my receipt but could't find it but i'm pretty sure i only paid like six bucks for them.

 

Can anyone suggest where to find new ones? Racambi wants $50 bucks each! Yikes! Someone have a good used one they want to sell? Just noticed that FerrParts.com has for $31.93. Thanks for the lead.

 

Dennis McCann has them for $22 that is where I got teh one I needed
Part number 60788100 (at least for 1982)

These door jam switches are the same as used in the Fiat X1/9. Much cheaper thru Fiat parts suppliers, same part.
