hello i just bought my first saab, a 1990 9000 turbo 2.0 and i love it but i have no heat i calibrated the acc system and had no fault codes come up everything works but the blower motor isnt blowing any heat ive checked the fuses and their all good but the fans are not coming on the blower motor was replaced by the previous owner about 8 months ago then it sat in his garage for awhile and when he brought it to me no heat could somebody tell me where i can find the relay for the blower motor and maybe give me some ideas on what the problem might be. thanks for any help
