have a 118 wheel base and they didn't offer rear ac so I was wondering if anyone has any ideas on how and where to buy upgraded compressors and blowers that will fit and make it colder cause it is hot in here

it's a taxi and I have the luggage compartment blocked off

 

no upgrade for front a/c, but could add rear

 

Make sure you check your cabin air filter. Mine was clogged and the A/C did not blow strong or very cold until I replaced that. It's at the firewall in the engine compartment.
