[Darla Mack]

I have a 1999 Lexus RX 300 I love my car my daughter drove it to Florida for me so that I could go home and take care of family while I was there in the meantime I had just put on a timing belt alternator starter breaks you know the usual maintenance stock a lot of money in her but she is worth it Run like a top so when she gets here the serpentine bout was squeaking a little and unbeknowns to me a friend of hers opened it up Thinking he was Mr. Fixed it I think instead of trying to tighten up the belt he broke the Old? Is serpentine belt is still running the car does kind of make a little bit of a noise the engine's Has never made before also he decided to clean out the fan because he thought there was a bird and I never saw a bird and the car ran fine except for the serpentine squeaking so he took a hose and sprayed water down into wherever cleaning out the fan supposed to play now I have no Dashlight radio seat power or moon wrote but I do have headlights and interior lights please please help me figure out what this is thank you so much Darla
