Its got a a/c leak they told me it is the evaporator but how can i be sure it is it.?

The best I can tell u is that the smell is from a leak at the evaporator or connections. I advise to get another opinion because it sounds like a lot of guesswork. if u get the work done, make sure the work comes with a warrantee! I gave all my customers warrantees for 20 years. That's part of the diagnostic business! Good Luck If u don't get a warrantee ,don't get the diagnosis or work done

Hi!

Please get a second opinion. It's very unlikely that evaporator itself is leaking. Usualy the leaks occur in joints between pipes.

Hope it helped.

Then I'd suggest starting your vehicle and checking for any vacuum leaks around your intake and replace any damaged hoses or reinstall them if any have came loose.

fuel systems are sealed. if there is a small air leak it will be detected called an evaporative system leak

could be pressure switch. When the guy put 134a in...find out what the pressure readings were on the suction line to find out if the compressor was working. May as well hook up the high side as well to get both readings. If there's a decent separation between the two....the compressor works. The evaporator is just a radiator, there's a metering device for the refrigerant into the evaporator, but the only thing that goes wrong with an evaporator is a leak.

replace ac evaporator

Under the dash??????

Could only mean the blower is bad

Or the blower motor resistor

Or the evaporator core if all the gas has leaked out

Have a pro look at it and determine for sure what the problem is.

1- If they find the leak in compressor, then only compressor needs to be changedwhy others have to be changed unless they see the leak at each port of others. I don't beleive they can see the leak at evaporator since they didn't touch your dash board, Only if they guarantee to make it work with 770 on all others, it is a very good price it the dash board labor is price included, You can ask to clear it up. If total price is lower than #2 then go for it.

2- The 1600 price is the same as few years back. I like this place because because they tell you up front having to pull out the dash board, to get to the evaporator. You have to see how hard to get the evaporator out to work. Because refrigerant and labor are expensive in troubleshooting, they want to repacle all for sure. Good luck on making a good deal.

the dealer does not want problems with somthing they just fixed so they tend to replace more than needed to be on the safe side ask around and find a good local mom & pop shop they should treat you right

If they have already checked the system by injecting a dye in with the freon and no leak detected in the engine area with the black light which will show any leak as a bright yellow, then the most likley area is the evaporator which is behind the right side dash.
