On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about about air conditioning service for your vehicle. Special guest includes Mesa Auto Works. Also on this show:

• My air conditioning is blowing hot. What is the problem?
• My car air conditioning isn't as cold as it should be.
• The air conditioning is blowing intermittently. Is there something wrong with my electrical system?
• What is an evacuate and re-charge service?
• 2005 Mercury Montego: The air blowing cool while I'm driving but when I come to a stop, it begins blowing warm air.
• 2012 Ford Escape: I used to get about 29mpg but when I put new tires on, it dropped down to 26 mpg. Is this normal?
• 2003 Chevy Trailblazer: The vehicle is blowing back and forth from warm to cool ever 6-7 minutes. Is this a charge problem?
• 2004 Mazda Protege: I was given as estimate of $1000 for a new air conditioning condenser. Is it okay to look for a used condenser in order to save money?
• 2005 Chevy Silverado 275,000 miles: I have a lifter making noise. If I run a heavier oil, will the ticking stop?
• 2005 Ford F350: When driving down the freeway, the car wanders and I'm constantly having to correct it.
• Before I had a car accident and had the front end worked on, my air conditioning blew ice cold. Now, it's not as cold any more.  
• 2007 Chevy Silverado 90,000 miles: The fluids are changed on a regular basis but the oil pressure light is staying on, there's a ticking noise and it's not leaking. What could the problem be?
• 2001 Chevy Malibu: The air is nice a cool but the compressor is making a rattling noise.
