Why Some Mechanics Recharge the AC Coolant in Older Chevy Trucks Rather Than Fix its Leak

Does your vehicle require refilling of its AC system refrigerant every few months? If so, then why hasn’t it been fixed? Here’s one take about some mechanics who would prefer charging you for refilling your refrigerant periodically rather than fixing a leaking refrigerant problem. Plus, an easy DIY tip that can help determine where your refrigerant is leaking when others have failed to locate the source.


AC Problems

In earlier articles we’ve discussed the problems and causes of an AC system that is blowing only hot air and what you can do about it before taking it to a mechanic.

However, did you know that taking it to a mechanic might not get the problem fixed correctly; but instead, wind up being serviced just enough to get you out of the garage for the next few months until your AC stops working again?

That’s the message in a recent Car Wizard YouTube channel episode where the Car Wizard does a show and tell about a 1999 Chevy Silverado that an owner recently bought used and wanted some minor issues taken care of that included a malfunctioning horn and an AC system with a constantly leaking refrigerant mystery problem.

The Value of this Show and Tell Video

What makes this video exceptional and worth recommending to watch is that it provides some especially useful information on why you will want to carefully inspect a used truck’s AC system before buying it that could make or break a truck buying deal.

In the video you will find out:

• The reason why some mechanics previously working on this vehicle either failed to find the problem and/or resorted to a temporary “fix” causing its owner to go elsewhere for help.

• How to approach the search for a refrigerant leak.

• A cool trick for finding one source of a mystery refrigerant leak.

• Some valid reasons why a mechanic might not want to help you fix your AC problem.

Please note: To pick up where the video discusses the AC leak diagnosis rather than watch the horn repair issue, start at timepoint 9:30 of the video and watch it to the end.

One of the best trucks on the road! Then why won't CAR WIZARD's techs work on this '99 Silverado?

Years ago, a company car, Ford Escort (late 80's) started blowing hot air. Took it to the local Ford dealer and they fixed it. In a few days started blowing hot air again. Turned out to the evaporator located in the dashboard. Obviously they didn't check that the first time. Replaced it and the A/C ran fine.
