The dealership told us that we need to have a module replaced on our 2005 Grand Cherokee that has to do with the ESP. They said that it was just a $10.00 part, but the total bill would be $105.00. Is this something that I can do myself and save a few bucks? I don't mind paying for a hours worth of labor, but I don't want to pay a hours worth of labor for a five minute job that I could have done myself. I experienced this with the TJ. They said that the purge solenoid was bad and it would be 1 to 2 hours of labor and $100.00 for the part. Well I bought the part from their parts counter for $25.00, did a little research on the net and found the location of the purge solenoid and had it changed out in 5 minutes. I cannot find any info about the ESP stuff on the net. Any and all help will be appreciated.
