Re: 91 deville ac problem

Sure it can be converted. Just like you did the other. The low side temperature sensor should be on the passengers side of the orifice tube I believe. Look for a coupler in the A/C line along the firewall. The orifice is at the coupler. Low pressure is on the passengers side of that. What I am saying is what I remember from my '97, but I think yours should be similar.
