Four problems related to tail light switch have been reported for the 1999 Jeep Grand Cherokee. The most recently reported issues are listed below.
Brake light failure on 1999 Jeep Grand Cherokee laredo- brake lights stop working when lights are turned on. Many similar complaints for the last 10 years on the web still no recall. Problem is defective contacts in the tail light assembly.
Rear passenger tail light does not work at night or rather when the car lights are turned on. Mechanic has replaced bulb, re-bent the connection, but the light still is not visible when lights are turned on. When lights are out, brake light, reverse light and turn signal work. My son has been pulled over by police thinking the lights had been fixed. Its only a matter of time before he receives a ticket. Our mechanic has offered to try and fix it without replacing both back light assemblies.
I recently purchased a 1999 Jeep Grand Cherokee. The driver side brake light on my Grand Cherokee does not work at all when the lights are turned on. When the lights are off during the day the light works fine, dimmer than the passenger side, but it still lights up. I have tried to fix the problem by changing out the bulbs and the pigtails the light goes into but I cant ever get it to work. I have noticed that every Grand Cherokee in the same generation as mine has the same problem I have talked to multiple mechanics that said they have fixed upwards of 50 gc's with that same problem and you must replace both taillight assemblies because if you replace one it will short out immediately. I work in the auto parts business so I have access to the parts to fix it but the taillight assemblies are around $140 a piece. I would think that Chrysler would have had a recall about it, seeing how common it is, but I have talked to my local dealer and they explained to me that it is up to NHTSA to issue a recall. I have received two tickets related to this incident. It becomes a hassle when I see all these Jeeps with the same problem and nothing has been done about it and the problem has been going on for years. I would appreciate it if you could look into this problem, seeing how it is such a common problem that Chrysler should take care of their defective products. Thanks a lot.
Consumer states turn signal lights stay on both sides, green lights are staying on all the time, headlights and tail lights are inoperable.
