As above. I have a 98 XSi. With A/C. On reading the threads for blower probs i think ive narrowed it down to something whats called an aux belt roller and idler pulley. Are these attached to the blower motor or would they be found somewhere else in service box? If found somewhere else need either proper name to search or P/N. Any direction to the right part would be good. Thanks.

Edit: No worries managed to find it in the end. Under the name AIR PULLER-AIR ENTRY-MODULE-REDUCER. (How to make life difficult)
