Chrysler Repair: Chrysler Lebaron Convertable fuse, chrysler lebaron, power door locks

Question
Roland,
I have a 91 Chrysler Lebaron Convertable. The motor that operates the convertable top suddenly stoped working. I am unable to locate the fuse for the motor. Do you know where it is located?
Thank You for any help!
Jeremy

Answer
Hi Jeremy,
There are two fuses, but unless you notice some other circuits are also out of order I suspect that the fuse is not your problem. The high current needed to power the motor comes from fuse cavity #3 where there is a circuit breaker rather than a fuse. It also operates the power seat motor, power door locks and the horn, so if you have functionning of any of those that is not the problem. The low current that switches on the relay to feed that high current comes from fuse cavity #5 that also powers the back-up lamps. Same issue, and you can look at the fuse too.
If it isn't the fuse, and you hear the relay in the motor area click when you operate the top switch, then you know that the switch is doing its job of throwing on the relay. If you don't hear a click, then you need to check the wiring from the switch to the relay, and again verify that 12V is getting to the switch from fuse #5. If you hear the click, and the power seat/ horn/ door locks work, then the other possibility is that the high current isn't getting to the relay (check at the relay, single red wire heavy gauge) and if it is then check at the motor disconnect to see it you get 12V on the red pin when you ask for raise, and 12V on the yellow pin when you ask for lower, both as compared to a ground point.
If you do then the motor brushes are probably worn out. If you don't then the relay internal contacts are bad. I believe you can replace the brushes, though I don't think they are available from Chrysler. You may have to take them out, go to a motor shop and get brushes of the same size but which are often too long and need to be filed down. At least that is what my cohorts at the Chrysler LeBaron Club of Yahoo tell me.
I own a LeBaron '89 coupe so alot of this response is based on reading circuit diagrams and heresay from other owners. But I think it is a correct assessment.
Good luck.
