A used one will work but a dealer is not permitted by the parent company to put anything other than new OEM or approved parts on their cars. You can have the work done at any good non-dealership shop that is not affiliated with chrysler. But, the unit needs to be coded before it will work properly.(flashed) which only a large well equipped shop can do.

I have 1995 jeep grand cherokee. bought used computer for it. can i program myself or do i need to take to dealer.


If the numbers on the two computer are the same, it should work. If they are different numbers, you may need to take it to a mechanic shop with the proper equipment needed to reprogram it.
I am curious as to why you bought a new computer; Did the old ecu die and not want to light up the check engine light or start the jeep any longer? If so, you could've had it repaired instead of buying another one and now possibly having to pay even more to reprogram it.

Have 99 grand cherokee & the horn isn't working & the airbag light is on what could be the problem?


The clock spring behind the sterring wheel is bad. This is the thing that allow all the electrical stuff in your sterring wheel to be able to work while you are turning the wheel. Sometimes this is recalled because of safety issues with the air bag. Check with local jeep dealer for recalls. 4 thumbs up is appreciated if this helps.

Need locations of all the themperature sensors on my 1996 Jeep Grand Cherokee Limited Edition 5.2 Liter, the dash says the Colant Sensor Is Bad, thought about punishing it :-), been doing this for about 3...


The Coolant Sensor is inside coolant bottle; in this models is common ths message failed; clean the plug and reset your ECU alarms, if the message come on again, replace your coolant sensor. And, really, one message about a bad sensor/signal is one bad work engine.

Good luck.
