On January 14, 2005, the station began stunting; after the stunt, the station officially signed on with a smooth jazz format as KJZN. This was the second station in Fresno to use the smooth jazz format, which was previously heard on KEZL (now KALZ).
On April 29, 2009, the station began stunting with Christmas music interspersed with Santa Claus-voiced liners which invited listeners to tune in at noon on May 1, if they "can handle the truth." At the promised time, the station flipped to a conservative talk format, branded as "105.5 The Truth."
On January 28, 2013, KJZN flipped to sports radio, branded as "105.5 The Game," with programming from the CBS Sports Radio Network.[3]
On November 25, 2014, KJZN and sister stationsKFRR and KJFX were purchased by One Putt Broadcasting from Wilks Broadcasting. The purchase was consummated on January 30, 2015.
On March 5, 2015 at 6 a.m., KJZN flipped to classic hip-hop. Initially set to be branded as "Bling 105.5”, One Putt instead held an online poll to determine the new name; in mid-March, the branding was revealed as "Rewind 105.5".[4]
On January 1, 2017, KJZN dropped the classic hip-hop format, flipped to Soft Adult Contemporary, and adopted the "K-Jewel" branding and KJWL call sign previously heard on 99.3 FM (now KJWL once again).[5] On January 5, 2017, KJZN officially changed its call sign to KJWL.
On May 23, 2022, it was announced that KJWL would move back to 99.3 FM on May 30, replacing the "Now FM" format on that frequency when it launched in 2017. A new permanent format was to debut at 105.5 FM after a month of simulcasting.[6]
On July 4, 2022, at 6 am, KJWL changed its format from classic hits to classic country, branded as "The Legend 105.5".[7] On July 9, 2022, the station took on the KWDO call sign.
