on a 93 Pontiac Bonneville you would remove the passenger side front tire. there may be a plastic cover that just pulls off. look to your left,back and up a little bit you should see the wires that connect to your cam sensor. theres your cam sensor. 91 Bonneville is probably the same.
It came from the factory with R12 Freon. It may have been converted to R134a. If so there should be a sticker near the compressor. If it has not been converted, I suggest you do so, as the price of Freon is prohibitive.
Probably the control unit mounted underneath the relays by the firewall. Get a used one somewhere, but get a new blower (parts store item) to go with it. That might save you from having to buy an other controller.
Actually there are three. 1)Under the plastic cover below the dashboard. 2)Inside the dash, next to the glove compartment. Remove the glove compartment for acess. 3)Under the hood on the firewall, under plastic cover.
No. The 96 is a 3800 Series II with different MAF sensor, fuel line attachments, fuel injectors and accessory attachments. The bolt pattern for the accessories is probably the most diffucult to overcome
I changed out the blower fan on my 89 without having to remove any of the a.c. The fan housing is against the firewall in the engine compartment. There is a two-wire connector going to it and a small rubber hose for condensation drainage
