1999 Jeep Grand Cherokee Gauges shutoff

While driving the car, the gauges turn off and the car stalls immediately. The car will not start until the gauges come back on. When the gauges are off, the car starter will turn over the engine, but it will not start. The first occurrence takes about 5-10 minutes before the gauges return, allowing the car to start immediately. The second occurrence takes about 15-25 minutes, and the car will start afterward. The third occurrence can take 40-60 minutes before the gauges come back on, and then the car will start. The stalls usually happen in stop-and-go traffic, while turning, or waiting at a traffic light, but never occur on the highway at high speeds. It is more likely to stall on hotter days, although sometimes it operates fine without stalling. Once the car stalls, it may stall again within 20-30 minutes, but this is not always the case. The vehicle has been to approximately seven repair shops, including a Jeep dealership, and has been assessed by around 20 mechanics. The engine trouble light is always illuminated, and the trouble codes have not been helpful. The seat belt light and key light are on while the gauges are off. Many parts have been replaced with no change in the issue. After several mechanics suggested that the problem might be with the computer, it was replaced, but the same problem persisted. There is frustration regarding any alarm systems that may have been installed, even if removed, as they could still be part of the circuit, sometimes just cut and taped without mechanical fasteners on the wires. There are undersized wires on the alarm relays. It is advisable to check all electrical connections and the thermostat, as there may be corrosion or damaged wiring that separates when heated. The issue seems to stem from an electrical problem.

It is noted that others have experienced similar problems, particularly in warmer weather, and inquiries about solutions have been made. A communication problem is suspected, especially if a "no bus" message appears on the cluster when the communication shuts down, leading to all systems being turned off and preventing the car from starting. The most probable issue is with the connectors, as two wires may be twisted together. It is also recommended to check the cluster connector, as problems may arise from faulty solder joints. The solder joints on the instrument panel circuit board may be deteriorating, leading to intermittent connections due to circular cracks in the solder. This condition can necessitate the removal and resoldering of various electronic items in different cars frequently.

In summary, the symptoms indicate a potential communication failure within the vehicle's electronic system, possibly due to poor connections or deteriorating solder joints on the instrument panel circuit board. Further investigation into the wiring and connections is essential, as these factors may contribute to the intermittent stalling and failure to start when the gauges are not operational.While driving car the gauges goes off and the car stall immediately. Car will not start until gauges come back on. While gauges are off the car starter will turn over the motor, but will not start. First time about 5-10 minutes before gauges are back on and then car starts immediately. Second time about 15-25 minutes before gauges are back on andthen car will start. Third time 40-60 minutes before gauges are back on and then car will start. Usually stalls in bumper to bumper traffic, while turning or waiting at a light. Never stalls on highway at high speeds. More likely to stall on hotter days. Some days works fine never stalls. Once car stalls it will usually stall again in about 20-30 minutes but not always. I usually try to take car home immediately after first stall and park it. Car has been to about 7 repair shops including Jeep dealership and probably looked at by about 20 mechanics. Engine trouble light always on and trouble codes no help. Seat belt light on and key light on while gauges are off. Many parts replaced with no change. After several mechanics insisted it had to be the computer. I finally let them replaced it and yes. no change. same problem. Very. frustrated any alarm systems that may have been installed. even if removed. they are still in the circuit. sometimes just cut and taped in. no mechanical fasteners on the wires. undersized wires on the alarm relays. you might want to check all the electrical connections and even the thermostat. Sometimes you might have a connection that has some corrosion in it or wiring that is damaged when it gets hot the connections might seperate due to the corrosion.

but it really sounds like an electrical issue. HELLO, I HAVE THE SAME PROBLEM WITH MY GCL 4. 7 USUALLY HAPPENS IN WARMER WEATHER, DID YOU FIND THE CURE. I SURE WOULD LIKE TO KNOW. THANKS PLEASE EMAIL ME AT MC717@YAHOO. COM WHEN YOU FIND OUT it`s more likely a communication problem, did you see a message "no bus" on the cluster when the communication shuts down all systems are shut off thus no start. most probable problem is the connector to the wires are 2 wires twisted together. check also the cluster connector some problems are the solder joints. what this answer was is the solder joints on the instrument panel circuit board are going bad. i have to remove various electronic items almost every week on various cars. to resolder them. the solder gets little circular cracks. this causes intermittent connections. it`s more likely a communication problem, did you see a message "no bus" on the cluster when the communication shuts down all systems are shut off thus no start.

Hello, I read a post that you put up stating that you had a problem with your GC. Sounds like the same thing that mine is doing. Mine is a 2000 Grand Cherokee Ltd and for the last couple months it will just shut down while driving for no apparant reason. When it does, all the guages go dead and all the dash indicator and warning lights come on. Each time it does not give a code but after letting the car sit for anywhere from 3 minutes to a couple hours it will always start again.

My question is. Does this sound like what was going on with your car Did you ever find out what the problem was If you could get back to me, I`d appreciate it. Check the mechanical operation of switch. Automatic Transmission: Be sure transmission lever is locked in PARK position after key removal. If key is difficult to rotate or is difficult to remov 🔗 External reference
