Hey again One more quik question. My a/c doesnt blow cold. How do i fix this? Thanks a lot James the quickest way is to have it serviced.... or you could be a bit more detailed in what you really mean by "doesn't blow cold".. >Hey again >One more quik question.

Griffiths, Pelican Parts, Vertex, providing you are in the USA but the first thing i would do is take to an a/c shop and have the system checked after that you can make the decision on what to fix... a diagnostic shouldn't run more then US $30-50 >"" wrote: > > agree with doug - short posts like that sound like trolling.

You should also replace the receiver/dryer ($20-30), as the dessicant is not compatible with R134 systems. But first have your system checked out to make sure it isn't leaking. If it's not blowing cold because the R12 leaked out, it prolly won't blow cold for long - just until the R134 leaks out. I've read that if your conversion kit uses PAG oil, you have to make sure you get all the current mineral oil out as the two won't mix and may clump together - same for the older ester oils. A synthetic ester (PolyOl ester, or POL) is supposedly compatible with both PAG and mineral oil. I have a conversion kit and am about to make the switch after I get some time. >"" wrote: > > a conversion kit costs about $20 to $30 with the fittings and [quoted text clipped - 40 lines] > > Drivers side wheel arch at the top near the fender edge insode the engine compartment > >do you know wher the high presure valve is located? > > > Drivers side wheel arch at the top near the fender edge insode the > engine compartment Doug, I'm assuming that's for left-hand drive (NA) cars? Where's the low side valve (this would be where the refrigerant goes in)? Specifically, for an '86. I've read: 1) that it's near the position you described, near the airbox, and 2) that it's underneath the car, left front corner, and 3) on the condenser itself Haven't tried looking for it myself yet because I'm waiting for some new hood struts so I don't have to hold/prop the hood up (did briefly look when I checked the oil and a few other things on my recently purchased '86 and saw two valves next to each other in the spot you mentioned). Thanks in advance. Low pressure fill input is on the compressor. Also, look up a product called "autofrost" on the net for a better low cost refrigerant. > Low pressure fill input is on the compressor. I was looking at the Porsche Factory Workshop Manuals and there's a note on the bottom of a page that as of the '87 model year, the low pressure fill is on the compressor. Sadly, I have an '86. > Also, look up a product > called "autofrost" on the net for a better low cost refrigerant. Thanks, looks interesting but I already have the r134a. Curious, though, for future info - is it a direct refill for R12 (evacuate the R12 and replace with Autofrost) or do you need to do anything else? Does it use the R12 mineral oil, or is PAG used? the low side is under the car, about 3 inches from where the hose goes into the compressor (at least that is where it was on mine) > > [quoted text clipped - 24 lines] > > it "" wrote: > the quickest way is to have it serviced.... > [quoted text clipped - 9 lines] > > > > hey Thanks for the response. What i mean by it not blowing cold is it like blows air the same temp the the air actually in the car is. the compressor turns on. |
