I believe you're referring to the HVAC Resistor unit - there were at least two versions but the second was used on the climate controlled models (2000 and later I believe). Both units are shared with Troopers and correspond with the same climate controls I believe - if you go to parts catalogs they're the same parts and should be the same prices. The later unit is quite expensive, the earlier less so - try sourcing it locally before paying the ridiculous shipping across the pond.
