Hello all,

Please help this damsel in distress!

My 1997 E 420's AC isnt cooling. I want to refill the R134A and don't know how?

My hubby will help, but I need instructions....

No cooling... just a fan running.....

Also, how expensive can it get for a mechanic to do this.. ( Someone told me it might run a few$$$)

Can someone please help me?

go buy a can.. youll need 2 lbs about. put in 1 can then try it. there is a fitting thatyou will screw on the R134 hose to on the AC meatl lines. it will only fit on one fitting.

 

Where is the low pressure refill valve on the E420 , 1997.

Thanks
