So I just noticed in my newly purchased 99 LS400 that that AC doesn't not work; I think the compresser comes on (the AC light does not blink), but it just never gets cold.

So I was looking for the low and high side AC lines, and it looks like the low side (near firewall, towards drivers side up near front) is missing its blue "L" cap! So I guess I've leaked all my cold goodness into the air.

So I have a R134A refill kit, but now my question is...how do I replace that cap??? It is something standard sized I should be able to find anywhere?

 

the dealer will have it but that cap isnt more than just a cover iirc.

recharging uses a 1-way valve system, just walk into ur local autoparts store and ask for a R134 recharge kit

 

cool thanks...I have the R134 recharge kit, gonna do it tomorrow
